It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '3.0.0-preview6.19307.2' was not found.

We are missing support for the Microsoft.AspNetCore.App shared runtime in source-build (https://github.com/dotnet/source-build/issues/375).

@omajid I think this should work now that https://github.com/dotnet/source-build/pull/1144 is in.

@crummel Just tried out commit ac534e8 and dotnet new web && dotnet run still fails:

Here's what I did:

Hmm, sorry about that. Let me try this on a clean machine.

[omajid]

@crummel Oh, nevermind.

See that /usr/lib64/dotnet in the output? I had DOTNET_ROOT set and that screws things up :( Unsetting makes things work :tada:
