Protractor combined with SpecFlow, Selenium and C#
Here is a great article from Anthony Chu that might help. There is a NuGet package for a .Net version of protractor that's built on top of Selenium. I've tried it and it works well with both nunit or SpecRunner. The C# version of protractor lets you use the same angular specific selectors that you get from protractor but runs it on top of the Chrome WebDriver.

Good Luck!
