Microsoft has been kind enough to release a number of free eBooks around their technology, and finally a number of them in a format besides PDF. If you want to read up one things like Azure, Windows Phone, SharePoint and Office here are some good starting points.
I recently was setting up a repository in a project with an interface on all repositories that took a predicate. As part of this I needed to mock out this call so I could unit test my code. The vast majority of samples out there for mocking an expression predicate just is It.IsAny<> which is not very helpful as it does not test anything other then verify it got a predicate. What if you actually want to test that you got a certain predicate though? It is actually pretty easy to do but not very straight forward.

Here is what it looks like when you want to pass in an exp
