Original Pull Request: https://github.com/adamhathcock/sharpcompress/pull/1049

State: closed
Merged: Yes

.NET 6 reached end-of-life November 2024. This updates target frameworks to drop net6.0, netstandard2.0, and net481, and add net10.0.

Target Frameworks

  • SharpCompress: net48;net8.0;net10.0 (removed net6.0, netstandard2.0, net481)
  • Test/Performance/Build projects: Updated to net10.0

SDK & CI

  • global.json: SDK 10.0.100
  • GitHub Actions: dotnet-version 10.0.x

.NET 10 Compatibility Fix

Rfc2898DeriveBytes constructor is obsolete in .NET 10 (SYSLIB0060). Updated to use static Pbkdf2 method:

#elif NET10_0_OR_GREATER
    var derivedKey = Rfc2898DeriveBytes.Pbkdf2(
        passwordBytes, salt, RFC2898_ITERATIONS,
        HashAlgorithmName.SHA1, derivedKeySize);
    KeyBytes = derivedKey.AsSpan(0, KeySizeInBytes).ToArray();
    IvBytes = derivedKey.AsSpan(KeySizeInBytes, KeySizeInBytes).ToArray();

Package Updates

<issue_description>Now that dotnet 10 is out, dotnet 6 should be dropped.

Probably dropping net standard too?

Should double check supported frameworks against windows.</issue_description>
