Azure Function CI build

Trying to set up CI for a series of Azure Functions (pre-compiled assemblies) but struggling. New pre-release VS2017.3 with Azure Function Tools extension and TeamCity running as build agent. Whenever I try to build a solution, I get a series of compiler errors:

If I compile the solution manually in VisualStudio, then the dependencies are resolved correctly after using the build agent. Fyi, I added a nuget restore step with NuGet v4.1 but no luck.

Any ideas? Or perhaps point me to a ps build script to create the final output structure (generated by the .json function, folder structure, etc.).

Update: Exit from nuget.exe restore phase:
