Answer 1

We implemented authenticated feed support in TeamCity plugin. Please follow comments to the issue http://youtrack.jetbrains.com/issue/TW-20764

Answer 2

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

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

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="Local" value="http://localhost:9090/httpAuth/app/nuget/v1/FeedService.svc" />
  </packageSources>
  <activePackageSource>
    <add key="Local" value="http://localhost:9090/httpAuth/app/nuget/v1/FeedService.svc" />
  </activePackageSource>
  <packageSourceCredentials>
    <Local>
      <Username>login</Username>
      <Password>pa$$w0rd</Password>
    </Local>
  </packageSourceCredentials>
</configuration>

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

This appears to be a known issue for TeamCity. The workaround suggests adding the package source via the command line client and then updating those sources with the authorization credentials:

nuget sources add -name [name] -source [feedUrl]
nuget sources update -Name [name] -User [username] -pass [password]

It's my understanding that Nuget will cache those credentials for future requests. I don't know how often that cache is cleared; you may need to run that nget sources update right before you kick off your build to ensure that the cache is coherent.
