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

Your combination of Mono MSBuild and .NET Core SDK is incompatible because they use different versions of the internal NuGet library. To resolve this problem, you can:

I had this error happen and the slove for me was correcting the Package version number in .csproj file .
<Version>2.0.7.</Version> <!--casued the error-->
<Version>2.0.7</Version> <!--this fixed the error-->
Removing the trailing '.' fixed this for me.
This appears to be a known issue.
The only fix at this stage seems to be to downgrade to .NET Core v2.2.105.
To downgrade:
I had the same problem using .Net Standard 2.1, and I solved it for myself by cleaning the solution and then rebuilding it.
Change the name of the file. For instance, Add prefix _ or #; so, it cannot be used.
Restart Visual Studio, then try to build. If still problem is there, needs to restart the machine.
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.
