Currently i'm working on a project to move an existing Silverlight application into AngularJS and there is one thing I've been missing while using Visual Studio that I had using Webstorm and that is syntax highlighting and auto-completion of angular directives.
I've made additions to the HTML 5 schema template in visual studio to get this working with Intellisense.
You can get the code from https://github.com/refactorthis/angularjs-visualstudio
And simply extract to
Common7\Packages\schemas\html in your Visual Studio install directory. For me that's
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Packages\schemas\html.
Overwrite the existing files and restart visual studio.
You should now have intellisense support for angular directives!
