Compiling application with LanguageExt as a dependency and ReadyToRun enabled using .NET 6 #66079
Description
Description
When compiling an application with .NET 5 and ReadyToRun enabled a binary is produced, trying to do the same with .NET 6 just "hangs". If a publish profile is used and -p:PublishReadyToRunCrossgen2ExtraArgs='--verbose' is provided it looks like crossgen2 is really busy processing all possible combinations of all possible generic classes. (That is more speculation from my side than anything else though)
Reproduction Steps
I've built a small application which can be found here; AndreSteenveld.CrossgenLanguageExt. Summarizing the readme; Running dotnet publish ./AndreSteenveld.CrossgenLanguageExt5.csproj -p:PublishSingleFile=true -p:PublishReadyToRun=true --configuration Release --runtime win-x64 --self-contained true produces a binary as expected. But doing the same for a .NET 6 project doesn't.
Expected behavior
I'm not expecting any super fast compilation, but nevertheless I do expect it to finish some time.
Actual behavior
Compile doesn't finish, even after several hours.
Regression?
I've read in the release notes that crossgen2 was released with .NET 6, so I'm assuming there is another (older) version of crossgen for .NET 5. So that would be my first suspect.

My compile target is also windows, x86-64. I do want to try to reproduce this on linux if possible, although I'm not expecting that it does compile (within a reasonable timeframe) on linux either.
