Feel like it used to be easier to get set up to contribute to .NET Core projects. I remember the days where things "just worked" but Arcade seems to cause loads of errors :(

[ViktorHofer]

Can you still repro this one? If yes, can you please add the /bl option and upload the binlog here?

[hughbe]

Yeah I could reproduce this in the following situation:

• Using dotnet msbuild ... instead of <repo-root>/.dotnet/dotnet msbuild ...

Guessing the first half is not a supported scenario?

What I did was uninstall .NET Core completely from my mac using the https://github.com/dotnet/cli/blob/master/scripts/obtain/uninstall/dotnet-uninstall-pkgs.sh script.

Then I'm building like: /Users/hugh/Documents/GitHub/corefx/.dotnet/dotnet msbuild /T:BuildAndTest

[ViktorHofer]

Which dotnet version have you had installed? The minimum required version is 3.0.0-preview6 (https://github.com/dotnet/corefx/blob/master/Documentation/building/windows-instructions.md) - I know this points to the windows instructions, we should probably put that into a more centralized place.

[ViktorHofer]

The first half is supported if the locally installed dotnet meets the minimum requirements

[hughbe]

I previously had 2.2.0 installed - this may have been the problem!

[ViktorHofer]

Oh right, you need at least 3.0-preview6. I'll close this issue.

[hughbe]

Amazing! I was under the impression that we symlinked the relevant SDK into the /usr/local/share/dotnet folder - at least I saw that in the output. How come therefore we can't use dotnet like we used to be able to before arcade?

[ViktorHofer]

You can use as it used to be before arcade. There was always a min version requirement, it just wasn't that important before as with 3.0.

[ViktorHofer]

Let me know if you need more help or if you think we update our docs :)

hi,

I have removed the line below in my csproj file. Worked.
