-# Plan: Implement Missing Async Functionality in SharpCompress
-
-SharpCompress has async support for low-level stream operations and Reader/Writer APIs, but critical entry points (Archive.Open, factory methods, initialization) remain synchronous. This plan adds async overloads for all user-facing I/O operations and fixes existing async bugs, enabling full end-to-end async workflows.
-
-## Steps
-
-1. **Add async factory methods** to [ArchiveFactory.cs](src/SharpCompress/Factories/ArchiveFactory.cs), [ReaderFactory.cs](src/SharpCompress/Factories/ReaderFactory.cs), and [WriterFactory.cs](src/SharpCompress/Factories/WriterFactory.cs) with `OpenAsync` and `CreateAsync` overloads accepting `CancellationToken`
-
-2. **Implement async Open methods** on concrete archive types ([ZipArchive.cs](src/SharpCompress/Archives/Zip/ZipArchive.cs), [TarArchive.cs](src/SharpCompress/Archives/Tar/TarArchive.cs), [RarArchive.cs](src/SharpCompress/Archives/Rar/RarArchive.cs), [GZipArchive.cs](src/SharpCompress/Archives/GZip/GZipArchive.cs), [SevenZipArchive.cs](src/SharpCompress/Archives/SevenZip/SevenZipArchive.cs)) and reader types ([ZipReader.cs](src/SharpCompress/Readers/Zip/ZipReader.cs), [TarReader.cs](src/SharpCompress/Readers/Tar/TarReader.cs), etc.)
-
-3. **Convert archive initialization logic to async** including header reading, volume loading, and format signature detection across archive constructors and internal initialization methods
-
-4. **Fix LZMA decoder async bugs** in [LzmaStream.cs](src/SharpCompress/Compressors/LZMA/LzmaStream.cs), [Decoder.cs](src/SharpCompress/Compressors/LZMA/Decoder.cs), and [OutWindow.cs](src/SharpCompress/Compressors/LZMA/OutWindow.cs) to enable true async 7Zip support and remove `NonDisposingStream` workaround
-
-5. **Complete Rar async implementation** by converting `UnpackV2017` methods to async in [UnpackV2017.cs](src/SharpCompress/Compressors/Rar/UnpackV2017.cs) and updating Rar20 decompression
-
-6. **Add comprehensive async tests** covering all new async entry points, cancellation scenarios, and concurrent operations across all archive formats in test files
-
-## Further Considerations
-
-1. **Breaking changes** - Should new async methods be added alongside existing sync methods (non-breaking), or should sync methods eventually be deprecated? Recommend additive approach for backward compatibility.
-
-2. **Performance impact** - Header parsing for formats like Zip/Tar is often small; consider whether truly async parsing adds value vs sync parsing wrapped in Task, or make it conditional based on stream type (network vs file).
-
-3. **7Zip complexity** - The LZMA async bug fix (Step 4) may be challenging due to state management in the decoder; consider whether to scope it separately or implement a simpler workaround that maintains correctness.

-# Plan: Modernize SharpCompress Public API
-
-Based on comprehensive analysis, the API has several inconsistencies around factory patterns, async support, format capabilities, and options classes. Most improvements can be done incrementally without breaking changes.
-
-## Steps
-
-1. **Standardize factory patterns** by deprecating format-specific static `Open` methods in [Archives/Zip/ZipArchive.cs](src/SharpCompress/Archives/Zip/ZipArchive.cs), [Archives/Tar/TarArchive.cs](src/SharpCompress/Archives/Tar/TarArchive.cs), etc. in favor of centralized [Factories/ArchiveFactory.cs](src/SharpCompress/Factories/ArchiveFactory.cs)
-
-2. **Complete async implementation** in [Writers/Zip/ZipWriter.cs](src/SharpCompress/Writers/Zip/ZipWriter.cs) and other writers that currently use sync-over-async, implementing true async I/O throughout the writer hierarchy
-
-3. **Unify options classes** by making [Common/ExtractionOptions.cs](src/SharpCompress/Common/ExtractionOptions.cs) inherit from `OptionsBase` and adding progress reporting to extraction methods consistently
-
-4. **Clarify GZip semantics** in [Archives/GZip/GZipArchive.cs](src/SharpCompress/Archives/GZip/GZipArchive.cs) by adding XML documentation explaining single-entry limitation and relationship to GZip compression used in Tar.gz
-
-## Further Considerations
-
-1. **Breaking changes roadmap** - Should we plan a major version (2.0) to remove deprecated factory methods, clean up `ArchiveType` enum (remove Arc/Arj or add full support), and consolidate naming patterns?
-
-2. **Progress reporting consistency** - Should `IProgress<ArchiveExtractionProgress<IEntry>>` be added to all extraction extension methods or consolidated into options classes?
-
-## Detailed Analysis
-
-### Factory Pattern Issues
-
-Three different factory patterns exist with overlapping functionality:
-
-1. **Static Factories**: ArchiveFactory, ReaderFactory, WriterFactory
-2. **Instance Factories**: IArchiveFactory, IReaderFactory, IWriterFactory
-3. **Format-specific static methods**: Each archive class has static `Open` methods
-
-**Example confusion:**
-```csharp
-// Three ways to open a Zip archive - which is recommended?
-var archive1 = ArchiveFactory.Open("file.zip");
-var archive2 = ZipArchive.Open("file.zip");
-var archive3 = ArchiveFactory.AutoFactory.Open(fileInfo, options);
-```
-
-### Async Support Gaps
-
-Base `IWriter` interface has async methods, but writer implementations provide minimal async support. Most writers just call synchronous methods:
-
-```csharp
-public virtual async Task WriteAsync(...)
-{
-    // Default implementation calls synchronous version
-    Write(filename, source, modificationTime);
-    await Task.CompletedTask.ConfigureAwait(false);
-}
-```
-
-Real async implementations only in:
-- `TarWriter` - Proper async implementation
-- Most other writers use sync-over-async
-
-### GZip Archive Special Case
-
-GZip is treated as both a compression format and an archive format, but only supports single-entry archives:
-
-```csharp
-protected override GZipArchiveEntry CreateEntryInternal(...)
-{
-    if (Entries.Any())
-    {
-        throw new InvalidFormatException("Only one entry is allowed in a GZip Archive");
-    }
-    // ...
-}
-```
-
-### Options Class Hierarchy
-
-```
-OptionsBase (LeaveStreamOpen, ArchiveEncoding)
-  ├─ ReaderOptions (LookForHeader, Password, DisableCheckIncomplete, BufferSize, ExtensionHint, Progress)
-  ├─ WriterOptions (CompressionType, CompressionLevel, Progress)
-  │   ├─ ZipWriterOptions (ArchiveComment, UseZip64)
-  │   ├─ TarWriterOptions (FinalizeArchiveOnClose, HeaderFormat)
-  │   └─ GZipWriterOptions (no additional properties)
-  └─ ExtractionOptions (standalone - Overwrite, ExtractFullPath, PreserveFileTime, PreserveAttributes)
-```
-
-**Issues:**
-- `ExtractionOptions` doesn't inherit from `OptionsBase` - no encoding support during extraction
-- Progress reporting inconsistency between readers and extraction
-- Obsolete properties (`ChecksumIsValid`, `Version`) with unclear migration path
-
-### Implementation Priorities
-
-**High Priority (Non-Breaking):**
-1. Add API usage guide (Archive vs Reader, factory recommendations, async best practices)
-2. Fix progress reporting consistency
-3. Complete async implementation in writers
-
-**Medium Priority (Next Major Version):**
-1. Unify factory pattern - deprecate format-specific static `Open` methods
-2. Clean up options classes - make `ExtractionOptions` inherit from `OptionsBase`
-3. Clarify archive types - remove Arc/Arj from `ArchiveType` enum or add full support
-4. Standardize naming across archive types
-
-**Low Priority:**
-1. Add BZip2 archive support similar to GZipArchive
-2. Complete obsolete property cleanup with migration guide
-
-### Backward Compatibility Strategy
-
-**Safe (Non-Breaking) Changes:**
-- Add new methods to interfaces (use default implementations)
-- Add new options properties (with defaults)
-- Add new factory methods
-- Improve async implementations
-- Add progress reporting support
-
-**Breaking Changes to Avoid:**
-- ❌ Removing format-specific `Open` methods (deprecate instead)
-- ❌ Changing `LeaveStreamOpen` default (currently `true`)
-- ❌ Removing obsolete properties before major version bump
-- ❌ Changing return types or signatures of existing methods
-
-**Deprecation Pattern:**
-- Use `[Obsolete]` for one major version
-- Use `[EditorBrowsable(EditorBrowsableState.Never)]` in next major version
-- Remove in following major version

-# NuGet Release Workflow
-
-This document describes the automated NuGet release workflow for SharpCompress.
-
-## Overview
-
-The `nuget-release.yml` workflow automatically builds, tests, and publishes SharpCompress packages to NuGet.org when:
-- Changes are pushed to the `master` or `release` branch
-- A version tag (format: `MAJOR.MINOR.PATCH`) is pushed
-
-The workflow runs on both Windows and Ubuntu, but only the Windows build publishes to NuGet.
-
-## How It Works
-
-### Version Determination
-
-The workflow automatically determines the version based on whether the commit is tagged using C# code in the build project:
-
-1. **Tagged Release (Stable)**:
-   - If the current commit has a version tag (e.g., `0.42.1`)
-   - Uses the tag as the version number
-   - Published as a stable release
-
-2. **Untagged Release (Prerelease)**:
-   - If the current commit is NOT tagged
-   - Creates a prerelease version based on the next minor version
-   - Format: `{NEXT_MINOR_VERSION}-beta.{COMMIT_COUNT}`
-   - Example: `0.43.0-beta.123` (if last tag is 0.42.x)
-   - Published as a prerelease to NuGet.org (Windows build only)
-
-### Workflow Steps
-
-The workflow runs on a matrix of operating systems (Windows and Ubuntu):
-
-1. **Checkout**: Fetches the repository with full history for version detection
-2. **Setup .NET**: Installs .NET 10.0
-3. **Determine Version**: Runs `determine-version` build target to check for tags and determine version
-4. **Update Version**: Runs `update-version` build target to update the version in the project file
-5. **Build and Test**: Runs the full build and test suite on both platforms
-6. **Upload Artifacts**: Uploads the generated `.nupkg` files as workflow artifacts (separate for each OS)
-7. **Push to NuGet**: (Windows only) Runs `push-to-nuget` build target to publish the package to NuGet.org using the API key
-
-All version detection, file updates, and publishing logic is implemented in C# in the `build/Program.cs` file using build targets.
-
-## Setup Requirements
-
-### 1. NuGet API Key Secret
-
-The workflow requires a `NUGET_API_KEY` secret to be configured in the repository settings:
-
-1. Go to https://www.nuget.org/account/apikeys
-2. Create a new API key with "Push" permission for the SharpCompress package
-3. In GitHub, go to: **Settings** → **Secrets and variables** → **Actions**
-4. Create a new secret named `NUGET_API_KEY` with the API key value
-
-### 2. Branch Protection (Recommended)
-
-Consider enabling branch protection rules for the `release` branch to ensure:
-- Code reviews are required before merging
-- Status checks pass before merging
-- Only authorized users can push to the branch
-
-## Usage
-
-### Creating a Stable Release
-
-There are two ways to trigger a stable release:
-
-**Method 1: Push tag to trigger workflow**
-1. Ensure all changes are committed on the `master` or `release` branch
-2. Create and push a version tag:
-   ```bash
-   git checkout master  # or release
-   git tag 0.43.0
-   git push origin 0.43.0
-   ```
-3. The workflow will automatically trigger, build, test, and publish `SharpCompress 0.43.0` to NuGet.org (Windows build)
-
-**Method 2: Tag after pushing to branch**
-1. Ensure all changes are merged and pushed to the `master` or `release` branch
-2. Create and push a version tag on the already-pushed commit:
-   ```bash
-   git checkout master  # or release
-   git tag 0.43.0
-   git push origin 0.43.0
-   ```
-3. The workflow will automatically trigger, build, test, and publish `SharpCompress 0.43.0` to NuGet.org (Windows build)
-
-### Creating a Prerelease
-
-1. Push changes to the `master` or `release` branch without tagging:
-   ```bash
-   git checkout master  # or release
-   git push origin master  # or release
-   ```
-2. The workflow will automatically:
-   - Build and test the project on both Windows and Ubuntu
-   - Publish a prerelease version like `0.43.0-beta.456` to NuGet.org (Windows build)
-
-## Troubleshooting
-
-### Workflow Fails to Push to NuGet
-
-- **Check the API Key**: Ensure `NUGET_API_KEY` is set correctly in repository secrets
-- **Check API Key Permissions**: Verify the API key has "Push" permission for SharpCompress
-- **Check API Key Expiration**: NuGet API keys may expire; create a new one if needed
-
-### Version Conflict
-
-If you see "Package already exists" errors:
-- The workflow uses `--skip-duplicate` flag to handle this gracefully
-- If you need to republish the same version, delete it from NuGet.org first (if allowed)
-
-### Build or Test Failures
-
-- The workflow will not push to NuGet if build or tests fail
-- Check the workflow logs in GitHub Actions for details
-- Fix the issues and push again
-
-## Manual Package Creation
-
-If you need to create a package manually without publishing:
-
-```bash
-dotnet run --project build/build.csproj -- publish
-```
-
-The package will be created in the `artifacts/` directory.
-
-## Build Targets
-
-The workflow uses the following C# build targets defined in `build/Program.cs`:
-
-- **determine-version**: Detects version from git tags and outputs VERSION and PRERELEASE variables
-- **update-version**: Updates VersionPrefix, AssemblyVersion, and FileVersion in the project file
-- **push-to-nuget**: Pushes the generated NuGet packages to NuGet.org (requires NUGET_API_KEY)
-
-These targets can be run manually for testing:
-
-```bash
-# Determine the version
-dotnet run --project build/build.csproj -- determine-version
-
-# Update version in project file
-VERSION=0.43.0 dotnet run --project build/build.csproj -- update-version
-
-# Push to NuGet (requires NUGET_API_KEY environment variable)
-NUGET_API_KEY=your-key dotnet run --project build/build.csproj -- push-to-nuget
-```

-# Testing Guide for NuGet Release Workflow
-
-This document describes how to test the NuGet release workflow.
-
-## Testing Strategy
-
-Since this workflow publishes to NuGet.org and requires repository secrets, testing should be done carefully. The workflow runs on both Windows and Ubuntu, but only the Windows build publishes to NuGet.
-
-## Pre-Testing Checklist
-
-- [x] Workflow YAML syntax validated
-- [x] Version determination logic tested locally
-- [x] Version update logic tested locally
-- [x] Build script works (`dotnet run --project build/build.csproj`)
-
-## Manual Testing Steps
-
-### 1. Test Prerelease Publishing (Recommended First Test)
-
-This tests the workflow on untagged commits to the master or release branch.
-
-**Steps:**
-1. Ensure `NUGET_API_KEY` secret is configured in repository settings
-2. Create a test commit on the `master` or `release` branch (e.g., update a comment or README)
-3. Push to the `master` or `release` branch
-4. Monitor the GitHub Actions workflow at: https://github.com/adamhathcock/sharpcompress/actions
-5. Verify:
-   - Workflow triggers and runs successfully on both Windows and Ubuntu
-   - Version is determined correctly (e.g., `0.43.0-beta.XXX` if last tag is 0.42.x)
-   - Build and tests pass on both platforms
-   - Package artifacts are uploaded for both platforms
-   - Package is pushed to NuGet.org as prerelease (Windows build only)
-
-**Expected Outcome:**
-- A new prerelease package appears on NuGet.org: https://www.nuget.org/packages/SharpCompress/
-- Package version follows pattern: `{NEXT_MINOR_VERSION}-beta.{COMMIT_COUNT}`
-
-### 2. Test Tagged Release Publishing
-
-This tests the workflow when a version tag is pushed.
-
-**Steps:**
-1. Prepare the `master` or `release` branch with all desired changes
-2. Create a version tag (must be a pure semantic version like `MAJOR.MINOR.PATCH`):
-   ```bash
-   git checkout master  # or release
-   git tag 0.42.2
-   git push origin 0.42.2
-   ```
-3. Monitor the GitHub Actions workflow
-4. Verify:
-   - Workflow triggers and runs successfully on both Windows and Ubuntu
-   - Version is determined as the tag (e.g., `0.42.2`)
-   - Build and tests pass on both platforms
-   - Package artifacts are uploaded for both platforms
-   - Package is pushed to NuGet.org as stable release (Windows build only)
-
-**Expected Outcome:**
-- A new stable release package appears on NuGet.org
-- Package version matches the tag
-
-### 3. Test Duplicate Package Handling
-
-This tests the `--skip-duplicate` flag behavior.
-
-**Steps:**
-1. Push to the `release` branch without making changes
-2. Monitor the workflow
-3. Verify:
-   - Workflow runs but NuGet push is skipped with "duplicate" message
-   - No errors occur
-
-### 4. Test Build Failure Handling
-
-This tests that failed builds don't publish packages.
-
-**Steps:**
-1. Introduce a breaking change in a test or code
-2. Push to the `release` branch
-3. Verify:
-   - Workflow runs and detects the failure
-   - Build or test step fails
-   - NuGet push step is skipped
-   - No package is published
-
-## Verification
-
-After each test, verify:
-
-1. **GitHub Actions Logs**: Check the workflow logs for any errors or warnings
-2. **NuGet.org**: Verify the package appears with correct version and metadata
-3. **Artifacts**: Download and inspect the uploaded artifacts
-
-## Rollback/Cleanup
-
-If testing produces unwanted packages:
-
-1. **Prerelease packages**: Can be unlisted on NuGet.org (Settings → Unlist)
-2. **Stable packages**: Cannot be deleted, only unlisted (use test versions)
-3. **Tags**: Can be deleted with:
-   ```bash
-   git tag -d 0.42.2
-   git push origin :refs/tags/0.42.2
-   ```
-
-## Known Limitations
-
-- NuGet.org does not allow re-uploading the same version
-- Deleted packages on NuGet.org reserve the version number
-- The workflow requires the `NUGET_API_KEY` secret to be set
-
-## Success Criteria
-
-The workflow is considered successful if:
-
-- ✅ Prerelease versions are published correctly with beta suffix
-- ✅ Tagged versions are published as stable releases
-- ✅ Build and test failures prevent publishing
-- ✅ Duplicate packages are handled gracefully
-- ✅ Workflow logs are clear and informative

 ## Code Formatting
 
-**Copilot agents: You MUST run the `format` task after making code changes to ensure consistency.**
-
 - Use CSharpier for code formatting to ensure consistent style across the project
 - CSharpier is configured as a local tool in `.config/dotnet-tools.json`
-
-### Commands
-
-1. **Restore tools** (first time only):
-   ```bash
-   dotnet tool restore
-   ```
-
-2. **Check if files are formatted correctly** (doesn't modify files):
-   ```bash
-   dotnet csharpier check .
-   ```
-   - Exit code 0: All files are properly formatted
-   - Exit code 1: Some files need formatting (will show which files and differences)
-
-3. **Format files** (modifies files):
-   ```bash
-   dotnet csharpier format .
-   ```
-   - Formats all files in the project to match CSharpier style
-   - Run from project root directory
-
-4. **Configure your IDE** to format on save using CSharpier for the best experience
-
-### Additional Notes
+- Restore tools with: `dotnet tool restore`
+- Format files from the project root with: `dotnet csharpier .`
+- **Run `dotnet csharpier .` from the project root after making code changes before committing**
+- Configure your IDE to format on save using CSharpier for the best experience
 - The project also uses `.editorconfig` for editor settings (indentation, encoding, etc.)
 - Let CSharpier handle code style while `.editorconfig` handles editor behavior
-- Always run `dotnet csharpier check .` before committing to verify formatting

 ### Zip Format Notes
@@ -35,18 +32,6 @@
 - Multi-volume/split ZIP archives require ZipArchive (seekable streams) as ZipReader cannot seek across volume files.
 - ZipReader processes entries from LocalEntry headers (which include directory entries ending with `/`) and intentionally skips DirectoryEntry headers from the central directory, as they are redundant in streaming mode - all entry data comes from LocalEntry headers which ZipReader has already processed.
 
-### 7Zip Format Notes
-
-- **Async Extraction Performance**: When using async extraction methods (e.g., `ExtractAllEntries()` with `MoveToNextEntryAsync()`), each file creates its own decompression stream to avoid state corruption in the LZMA decoder. This is less efficient than synchronous extraction, which can reuse a single decompression stream for multiple files in the same folder.
-  
-  **Performance Impact**: For archives with many small files in the same compression folder, async extraction will be slower than synchronous extraction because it must:
-  1. Create a new LZMA decoder for each file
-  2. Skip through the decompressed data to reach each file's starting position
-  
-  **Recommendation**: For best performance with 7Zip archives, use synchronous extraction methods (`MoveToNextEntry()` and `WriteEntryToDirectory()`) when possible. Use async methods only when you need to avoid blocking the thread (e.g., in UI applications or async-only contexts).
-  
-  **Technical Details**: 7Zip archives group files into "folders" (compression units), where all files in a folder share one continuous LZMA-compressed stream. The LZMA decoder maintains internal state (dictionary window, decoder positions) that assumes sequential, non-interruptible processing. Async operations can yield control during awaits, which would corrupt this shared state. To avoid this, async extraction creates a fresh decoder stream for each file.
-
 ## Compression Streams
 
 For those who want to directly compress/decompress bits. The single file formats are represented here as well. However, BZip2, LZip and XZ have no metadata (GZip has a little) so using them without something like a Tar file makes little sense.

+## Async Usage
+
+SharpCompress now provides full async/await support for all I/O operations, allowing for better performance and scalability in modern applications.
+
+### Async Reading Examples
+
+Extract entries asynchronously:
+```csharp
+using (Stream stream = File.OpenRead("archive.zip"))
+using (var reader = ReaderFactory.Open(stream))
+{
+    while (reader.MoveToNextEntry())
+    {
+        if (!reader.Entry.IsDirectory)
+        {
+            // Async extraction
+            await reader.WriteEntryToDirectoryAsync(
+                @"C:\temp",
+                new ExtractionOptions() { ExtractFullPath = true, Overwrite = true },
+                cancellationToken
+            );
+        }
+    }
+}
+```
+
+Extract all entries to directory asynchronously:
+```csharp
+using (Stream stream = File.OpenRead("archive.tar.gz"))
+using (var reader = ReaderFactory.Open(stream))
+{
+    await reader.WriteAllToDirectoryAsync(
+        @"C:\temp",
+        new ExtractionOptions() { ExtractFullPath = true, Overwrite = true },
+        cancellationToken
+    );
+}
+```
+
+Open entry stream asynchronously:
+```csharp
+using (var archive = ZipArchive.Open("archive.zip"))
+{
+    foreach (var entry in archive.Entries.Where(e => !e.IsDirectory))
+    {
+        using (var entryStream = await entry.OpenEntryStreamAsync(cancellationToken))
+        {
+            // Process stream asynchronously
+            await entryStream.CopyToAsync(outputStream, cancellationToken);
+        }
+    }
+}
+```
+
+### Async Writing Examples
+
+Write files asynchronously:
+```csharp
+using (Stream stream = File.OpenWrite("output.zip"))
+using (var writer = WriterFactory.Open(stream, ArchiveType.Zip, CompressionType.Deflate))
+{
+    await writer.WriteAsync("file1.txt", fileStream, DateTime.Now, cancellationToken);
+}
+```
+
+Write all files from directory asynchronously:
+```csharp
+using (Stream stream = File.OpenWrite("output.tar.gz"))
+using (var writer = WriterFactory.Open(stream, ArchiveType.Tar, new WriterOptions(CompressionType.GZip)))
+{
+    await writer.WriteAllAsync(@"D:\files", "*", SearchOption.AllDirectories, cancellationToken);
+}
+```
+
+All async methods support `CancellationToken` for graceful cancellation of long-running operations.

 ### Extract all files from a rar file to a directory using RarArchive
 
 Note: Extracting a solid rar or 7z file needs to be done in sequential order to get acceptable decompression speed.
-`ExtractAllEntries` is primarily intended for solid archives (like solid Rar) or 7Zip archives, where sequential extraction provides the best performance. For general/simple extraction with any supported archive type, use `archive.WriteToDirectory()` instead.
+It is explicitly recommended to use `ExtractAllEntries` when extracting an entire `IArchive` instead of iterating over all its `Entries`.
+Alternatively, use `IArchive.WriteToDirectory`.
 
 ```C#
 using (var archive = RarArchive.Open("Test.rar"))
 {
-    // Simple extraction with RarArchive; this WriteToDirectory pattern works for all archive types
-    archive.WriteToDirectory(@"D:\temp", new ExtractionOptions()
