In the same way that you would expect "AngularJS for Node Developers" to include information on running your app using a Node.js backend, this has information on using a .NET backend.
Also, another thing that bothers me about MS is that they hide so much real HTML/javascript from devs with visual basic like facade called webforms that MS devs don't get into a new platform unless they see a document like "Angular js for .net" title.
Microsoft is moving even further in that direction with Web API, which does largely transform ASP.NET into a "dumb" REST endpoint completely separate from the HTML/JS clientside.
