The 3.1.3 Release Notes links to an internal page for macOS Notarization Issues instead of https://docs.microsoft.com/en-us/dotnet/core/install/macos-notarization-issues

Thanks @mletterle - link fixed.

@fwd079 - the Chocolatey packages are community maintained and not "official". We'll check a few things on this side to make sure nothing is obviously out of sorts. After that, it will be up to the maintainers.

Update: If I run choco search dotnetcore, 3.1.2 is reported even though https://chocolatey.org/packages/dotnetcore indicates 3.1.3.

@riezebosch - any thoughts?

[riezebosch]

something went wrong on publishing the package, it seems available but you cannot download it: https://packages.chocolatey.org/dotnetcore-runtime.install.3.1.3.nupkg

Pushed an update

Just successfully installed 3.1.3 and SDK 3.1.201 via Chocolatey. Looks like that did it. Thanks @riezebosch!

So it was on this side, well I am glad then, since that made sorting out a swift thing, checked this morning and working as expected and installed.

Thanks @riezebosch for looking into it.

The following relates to 3.1.3.

When restoring an fsproj project with SDK version 3.1.201, I am seeing this:

 /root/.nuget/packages/microsoft.build.tasks.git/1.0.0-beta2-19270-01/build/Microsoft.Build.Tasks.Git.targets(16,5): error MSB4018: The "Microsoft.Build.Tasks.Git.LocateRepository" task failed unexpectedly. [foo.fsproj]
 /root/.nuget/packages/microsoft.build.tasks.git/1.0.0-beta2-19270-01/build/Microsoft.Build.Tasks.Git.targets(16,5): error MSB4018: System.TypeInitializationException: The type initializer for 'Microsoft.Build.Tasks.Git.TaskImplementation' threw an exception. [foo.fsproj]
 /root/.nuget/packages/microsoft.build.tasks.git/1.0.0-beta2-19270-01/build/Microsoft.Build.Tasks.Git.targets(16,5): error MSB4018:  ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Build.Tasks.Git, Version=1.0.0.27001, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified. [foo.fsproj]

If I use 3.1.103, it works fine. Only 3.1.201 has the problem.

I see the same pattern with release 3.1.2. Problem exists in 3.1.200 but it works in 3.1.102. I have tried both in Docker to isolate any VS-related issues.

I wonder if the problem has to do with the version of MSBuild tools/dependencies in .201 and .200 being outdated? But they're good enough for .103 and .102, which I note targets a slightly older Visual Studio.

Command used was dotnet test -c Release foo.fsproj.

I get the same problem running under a Docker build with image mcr.microsoft.com/dotnet/core/sdk:3.1.201. (To my knowledge, there is no sdk:3.1.103, so I can't check that.)

Is there any more information I can provide? Should I file an issue on this somewhere?
