Creating classlibrary and trying to install Markdig.

I can use usings in code, but I'm trying to start debugging and it throws it:

link to library.

Here is my .csproj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <RootNamespace>Kvyk.Telegraph.Markdown</RootNamespace>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Kvyk.Telegraph" Version="1.0.2" />
    <PackageReference Include="Markdig" Version="0.25.0" />

Just tried and it is working on my machine, it's working on the CI and it's working also for many users, with 2000+ download per day, we would get a substantial number of issues like that if Markdig was not working like you describe.

So you might have something wrong on your machine. Maybe try to setup a global.json which restrict to net5.0 SDK and/or remove any superfluous dotnet SDK installed. Try to install a new version of dotnet SDK 5.0. Cleanup maybe your NuGet cache folders...etc. Have you installed a preview version of VS like VS 2022? That could break things like that... but it could be anything, even a global env variable that is messing with msbuild. You can investigate yourself such issues by checking the log of msbuild...etc.

I found the solution. In my test project were added dublicated references. I`ve created net test project for project I need to test an it works now.
