Looking to debug System.Net.Http.WinHttpHandler

[jensolsson]

I believe I spotted an issue with HTTP/2 in WinHttpHandler and want to investigate it further. I pulled the code and included System.Net.Http.WinHttpHandler.csproj in my solution but I am unable to compile and run it.

I get the following error in the log file from Visual Studio

2020-08-13 12:53:23
Recoverable
System.AggregateException: Project system data flow 'DataflowBlockSlim (ActionBlockSlimAsync1 : 25115887)' closed because of an exception: System.AggregateException: One or more errors occurred. ---> System.ArgumentException: Must contain activeTargetFramework (Unsupported,Version=v0.0). Parameter name: dependenciesByTargetFramework at Microsoft.VisualStudio.ProjectSystem.VS.Tree.Dependencies.Snapshot.DependenciesSnapshot..ctor(String projectPath, ITargetFramework activeTargetFramework, ImmutableDictionary2 dependenciesByTargetFramework)
...

I also get some errors regarding nuget

Is it possible to include WinHttpHandler like this? What am I doing wrong?
