How to set up Teamcity for an ASP.net project under mono?

Question

Mono

Good time of the day!
There is an ASP.net application on git (vNext in the future) with nuget dependencies and NUnit tests. For Win machines, creating a Build Task was not difficult, but for Unix systems there are a number of difficulties:
1. Nuget how best to restore packages on Unix machines and how does it integrate into TC?
2.MSBuild Task for Unix swears on paths or their absence
3. Nunit didn't get to run the tests, but still.
Maybe there is a ready-made manual on how to start all this?
