Alternative to TfsTeamProjectCollectionFactory.GetTeamProjectCollection taking ICredentialsProvider

According to the MSDN the method GetTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentialsProvider fallbackCredentialsProvider of the TfsTeamProjectCollectionFactory class is now deprecated:

• "Note: This API is now obsolete."

• [ObsoleteAttribute("This method has been deprecated and will be removed in a future release. See GetTeamProjectCollection(RegisteredProjectCollection) instead.", false)]

The advice is to use the overload that only takes the RegisteredProjectCollection, but what should we use from now on if we want a fallback mechanism for credentials?

Thanks

You need to use the new TfsTeamProjectCollection constructor along with this TfsClientCredentials constructor which allows interactive prompts for authentication.

// Use default windows credentials, and if they fail, AllowInteractive=true
var tfsCreds = new TfsClientCredentials(new WindowsCredential(), true);

TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(
    new Uri("http://yourserver:8080/tfs/DefaultCollection"),
    tfsCreds);
