System.TypeLoadException: 'Could not resolve type 'System.AppContext'

[shmao]

I was trying to build serialization tests in CoreFx against uapaot. Sg.exe failed to resolve System.AppContext, which caused error when building the tests. Here's the error message,

System.TypeLoadException occurred
  HResult=0x80131522
  Message=Could not resolve type 'System.AppContext' in assembly 'System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

  StackTrace:

Is System.AppContext not available on uapaot?

Hi @myesn , the original bug tracked by this issue was found prior to the product release and was fixed. The error message you got may be identical with the error here, but I doubt they are the same issue.

Can you please provide more information regarding to the issue you're seeing? Please feel free to open a new issue for the problem you're having for better tracking.
