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.
I had .net standard project built on .net standard 2.0. Yesterday I updated my Visual Studio 2019 to 16.3.0 to leverage .Net Core 3.0. But all of sudden build of project targeting on standard 2.0 started throwing "GenerateDepsFile" task failed unexpectedly error.
I was able to resolve this issue by changing the target framework to 2.1.
