I'm looking for sample solution(s) that demonstrate various kinds of unit tests in C# using best practices. Also I require the examples to use the Visual Studio test tools. I know that there are a number of books and web sources on unit testing, but they don’t use the Visual Studio tools for writing their unit tests. I don’t want really basic examples such as can be found here. I am looking to move to the next level of unit-testing and I can’t find advanced examples of unit testing that use Visual Studio 2010 or even VS 2008.
EDIT: To be more clear; I am working on a project where I have to use the testing tools that are built in to Visual Studio. I am not looking for info on any 3rd party testing tools.
