[vitek-karas]

The error clearly states:

The framework 'Microsoft.AspNetCore.App', version '6.0.0' (x64) was not found.

Your machine doesn't have the Microsoft.AspNetCore.App framework installed, this can be seen in the output of dotnet --info, the section ".NET Runtimes installed" doesn't have any mention of it.

If you follow the link in the error it points you to a download page, the Linux version of that page has basically just one download which should install both Microsoft.NETCore.App framework as well as the missing Microsoft.AspNetCore.App.

[minskiter]

The problem also occurs on docker. It seems that the runtime version of 6.0-rc is different from the sdk.

@minskiter if you're still seeing the problem, could you please create a new issue? This one seems to be answered, so I'm going to close it. Please include the actual error you get.
