Great !.

What's about Branches and Merges?

I have create Branch

      int changesetId = vcServer.CreateBranch(sourcePath, targetPath, VersionSpec.Latest);
      Changeset changeset = vcServer.GetChangeset(changesetId);
        changeset.Comment = comment;
        changeset.Update();

I can get Changeset list

      var ChangesetList = vcServer.QueryHistory(targetPath,
              VersionSpec.Latest, 0, RecursionType.Full, "", versionFrom, VersionSpec.Latest,
              Int32.MaxValue,
              true, // the boolean "include changes" is taking the time... If you do not include the changes and only the metadata of the changesets the query is very fast
              false).Cast<Changeset>();

I can do Checkout and Checkin about files in Branch, and then do Merges.

I can use GetBranchHistory and QueryPendingSets.
I'm confused how get good infor about branches history , merges history (maybe QueryMergesWithDetails), and differences with QueryPendingSets.

Hey, sorry didn't see your comment till now.

I found showing branch and merge history very hard as well. I think it also depends on what exactly you would like to show. Here I was wanting only work items linked to changesets, and I get those through merge history as well.

I'm using a different chunk of code and I'm having trouble at this point: tfs.EnsureAuthenticated();

I get the error below.

TeamFoundationServiceUnavailableException: TF31002: Unable to connect to this Team Foundation Server: http://optimus:8080/tfs.
Team Foundation Server Url: http://optimus:8080/tfs.

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.
