Hello Vishnupriyan Radhamanalan, Mathew Aniyan
Just a quick message to let you know (if it was not the case) that the TFS 2015 Object Model now ships as a NuGet package and its license allows it to be redistributed. See http://blogs.msdn.com/b/buckh/archive/2015/08/10/nuget-packages-for-tfs-and-visual-studio-online-net-client-object-model.aspx

Thanks Dinesh.
Yes, we discussed about taking dependency on the TFS Object Model. However, we want to understand the compatibility between different versions - 2013, 2015. So, We will create a separate ticket to work on this.

With #48 I'm planning to switch to Microsoft.TeamFoundationServer.ExtendedClient package, which should solve this issue.

Fixed with #48.
