The "GenerateDepsFile" task failed unexpectedly

Question

I tried to compile my new application in MonoDevelop and I got this error:

/usr/share/dotnet/sdk/2.2.203/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(5,5): Error MSB4018: The "GenerateDepsFile" task failed unexpectedly.

I cannot compile any application. Please help.

Answer 1

I had the same problem using .Net Standard 2.1, and I solved it for myself by cleaning the solution and then rebuilding it.

Answer 2

Just moved my projects to a new machine (copying, not pulling from GIT) and started getting this. Deleting the bin and obj folders in each project solved this issue.
