Can't open VisualFSharp.sln, .NET SDK requirement?

[dsyme]

Opening VisualFSharp.sln with latest Visual Studio produces load warnings

Here are my installed .NET SDKs. I will try also installing .NET SDK 3.1.302 though I can't recall previously needing to do that

This resolves after globally installing the appropriate .NET SDK

Maybe our install scripts should just do/detect a global install of the thing

[cartermp]

This needs to be re-opened, FYI @brettfo @KevinRansom

This is a serious issue because we do not install this SDK version in either the build script or in any RTM or preview VS version. That makes contributing to this repo suck.

[KevinRansom]

We download 3.1.302 to here: C:\microsoft\fsharp.dotnet\sdk\3.1.302

That VS warns is because it doesn't really understand that we are using a non-globally installed sdk. That is the real problem.

If someone wants to spend some time and figuring out why VS does the wrong thing that would be good. Otherwise, one day Brett and I will spend the effort to figure it out.

In the mean time the work around is trivial install 3.1.302 from here: https://dotnet.microsoft.com/download/dotnet-core/3.1

[cartermp]

Note it is not a warning, it is an error. And whatever we download is not actually used. That's why I re-opened this.

Iirc, this didn't use to be an issue, running build installed dotnet in the local .dotnet directory. Opening Visualfsharp.sln after running a first build (optionally preceded with a git clean) recently worked flawlessly, I do it all the time.
