How do you connect to a TFS server in C# using specific credentials?

Question

I am attempting to write a c# application that connects to TFS and retrieves work item information. Unfortunately, it seems like all examples of using the TFS SDK are using

Answer 1

Years down the line, this is how you do it with TFS 2013 API:

// Connect to TFS Work Item Store
ICredentials networkCredential = new NetworkCredential(tfsUsername, tfsPassword, domain);
Uri tfsUri = new Uri(@"http://my-server:8080/tfs/DefaultCollection");
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(tfsUri, networkCredential);
WorkItemStore witStore = new WorkItemStore(tfs);

---

If that doesn't work, try to pass the credentials through other Credential classes (worked for me):

// Translate username and password to TFS Credentials
ICredentials networkCredential = new NetworkCredential(tfsUsername, tfsPassword, domain);
WindowsCredential windowsCredential = new WindowsCredential(networkCredential);
TfsClientCredentials tfsCredential = new TfsClientCredentials(windowsCredential, false);

// Connect to TFS Work Item Store
Uri tfsUri = new Uri(@"http://my-server:8080/tfs/DefaultCollection");
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(tfsUri, tfsCredential);
WorkItemStore witStore = new WorkItemStore(tfs);

Answer 2

The following code should help you:

NetworkCredential cred = new NetworkCredential("Username", "Password", "Domain");
tfs = new TeamFoundationServer("http://tfs:8080/tfs", cred);
tfs.EnsureAuthenticated();

Domain is either the actual domain, or in a Workgroup situation, it would be the name of the server that hosts the TFS Application Tier.

Answer 3

For TFS 2015 & 2017, objects and methods mentioned have been (or are being) deprecated.

To connect to TFS using specific credentials:

// For TFS 2015 & 2017

// Ultimately you want a VssCredentials instance so...
NetworkCredential netCred = new NetworkCredential(@"user.name", @"Password1", "DOMAIN");
WindowsCredential winCred = new WindowsCredential(netCred);
VssCredentials vssCred = new VssClientCredentials(winCred);

// Bonus - if you want to remain in control when
// credentials are wrong, set 'CredentialPromptType.DoNotPrompt'.
// This will thrown exception 'TFS30063' (without hanging!).
// Then you can handle accordingly.
vssCred.PromptType = CredentialPromptType.DoNotPrompt;

// Now you can connect to TFS passing Uri and VssCredentials instances as parameters
Uri tfsUri = new Uri(@"http://tfs:8080/tfs");
var tfsTeamProjectCollection = new TfsTeamProjectCollection(tfsUri, vssCred);

// Finally, to make sure you are authenticated...
tfsTeamProjectCollection.EnsureAuthenticated();
