1.0.0-beta2-19351-01 and Microsoft.Build.Tasks.Git.LocateRepository task failed unexpectedly

[wjvii]

Had a project using version 1.0.0-beta-63127-02 and updated to 1.0.0-beta2-19351-01 and started experiencing this error. I have tried this on three different project types, .NET Standard and .NET Framework and it occurs on both. I also tried a .NET Standard with targetframeowrk set to net472 and same issue. These were all brand new projects in the same git repo.

I'm getting this as well: dotnet/roslyn#28916
Found the solution. I had git installed in WSL, but not in Windows. It's probably good to have an error message for this.

@jcouv Git installation shouldn't be necessary. This is a bug.

I reproduce this bug also, I clone a repository and can't build since this issue.
