Answer 1

For your problem, normally you get an error like:

Possible reasons for failure include: - The name, port number, or protocol for the Team Foundation Server is incorrect. - The Team Foundation Server is offline. - The password has expired or is incorrect.

The root cause of your problem is that the URI should be ended up with the collection name. So the fix would be, to change "http://10.112.205.145:8080/tfs" to "http://10.112.205.145:8080/tfs/%YourCollectionName%", then it will work! :-)

Answer 2

A simple way to do this is to add the "Syetem.Net" namespace to your code and then use the "CredentialCache" object. Using "DefaultCredentials" will Authenticate with the credentials of the active user.

// connect to the collection
using (TfsTeamProjectCollection teamProjectCollection = new TfsTeamProjectCollection("http://server:8080/tfs/DefaultCollection", CredentialCache.DefaultCredentials))
            { 
                //Do Stuff here 
            }

Answer 3

Have you tried doing it this way..

TfsTeamProjectCollection collection = new TfsTeamProjectCollection(
    new Uri(http://server:8080/tfs/DefaultCollection,
    new System.Net.NetworkCredential("domain_name\\user_name", "pwd"));
collection.EnsureAuthenticated();
