var collection1 = new TfsTeamProjectCollection(new Uri("http://tfs:8080/tfs/collection"));

collection1.EnsureAuthenticated();

var ims = collection1.GetService<IIdentityManagementService>();

var id = ims.ReadIdentity(IdentitySearchFactor.AccountName, "domain\\username", MembershipQuery.None, ReadIdentityOptions.None);

var collection = new TfsTeamProjectCollection(new Uri("http://tfs:8080/tfs/collection"), id.Descriptor);

-- OR --

WorkItem wi;

...

// Change Work Item

...

// Set ChangedBy Field

wi[CoreField.ChangedBy] = userName;

wi.Save();
