TeamCity Nuget install build step not working with multiple sources, one of them TC's private NuGet feed

Question

I receive the following error in NuGet Install build step when setting sources to TeamCity\'s NuGet server:

Step 1/4: NuGet install (NuGet Installer) (3s)

[15:1         


        

Answer 1

You can specify custom feeds just for solution via nuget.config file.

The key point is to provide credentials section packageSourceCredentials like this:

  
    
  
  
    
  
  
    
      login
      pa$$w0rd
    
  

This config file should be next to the sln file in repository.
