Question

When Build Project. Error The "RazorGenerate" task failed unexpectedly. .Net Core 2.2

Answer 1

The fix for me was to introduce a new System Environment Variable with the Key "DOTNET_HOST_PATH" and the value "dotnet" and then to restart Visual Studio.

Answer 2

I did 3 steps to get it to build AND to get the ( ~/ ) variable to work.

1. Open cmd and write this: setx DOTNET_HOST_PATH "%ProgramFiles%\dotnet\dotnet.exe"
2. Open C:\Program Files\dotnet\sdk in here delete the folder: NuGetFallbackFolder
3. Restart your pc!
