Hi,
Thanks for not giving up yet :-)
What you say is true, the example show features that use Enterprise features TypeMock.NET too.
There is a readme file that is attached to the examples and many comments in the example code to help understand what is happening in the code.
You could benefit by running each test separately and understanding different aspects of Mocking.
You can run the tests separately in one of the following ways:
1. by using the TestDriven.NET addin
2. by using the NUnit GUI and running just that test
3. by using the NUnit console /fixture attribute.
When you want to test Enterprise Features you can turn on these features by selecting the Demo Mode in the TypeMock Configuration. There are restrictions in this mode, but you can run the tests and see how they work.
