I have the following code in the code-behind C# file of an ASP.NET application:

TeamFoundationServer tfs = TeamFoundationServerFactory.GetServer(m_strTeamSystemServer, new UICredentialsProvider();

tfs.EnsureAuthenticated();

Works fine when in my development environment inside the Visual Studio solution. Well, the connection to tfs works anyway. I don't get prompted for credentials.

The problem is when I copy the website to my deployment environment. When tfs.EnsureAuthenticated(); is called, the site just "hangs". It sits there in a loading state (this code is called in my Page_Load) forever, or at least until I got tired of waiting (5 minutes or so).

Any ideas what could be the problem here? Why don't I get a credentials dialog? I checked to make sure there was no popup blocker or anything running, and I see other javascript alert() dialogs without any issue.

Oh, I also tried using the TeamFoundationServer constructor instead of the TeamFoundationServerFactory and it made no difference.

If you are going to use the code in an ASP.NET site, do not specify a UICredentialsProvider to either the factory or the constructor. When you call EnsureAuthenticated() in that case, it will throw TeamFoundationServerUnauthorizedException if the current credentials fail to authenticate with the server. If you need to specify a particular set of credentials, you can supply them to the constructor.

The following may help: TFS API: How to choose between TeamFoundationServerFactory.GetServer() and the TeamFoundationServer constructor.

I finally resorted to just creating my own (very redundant) login form and create the credentials based on the user's input. I tried to get impersonation to work, but I got nothing from the DefaultNetworkCredentials object regardless of what my impersonation settings were. I got the expected login prompt when first loading the web site, but the DefaultNetworkCredentials remained blank. Anyway, it works well enough using my own login form, but it's definitely not my preferred design.
