Something I don't enjoy about programming is learning a new API. For example, right now I'm trying to learn Windows Identity Foundation. Its frustrating because I'm going to spend the bulk of the time learning how a few classes work and actually only write several lines of code.

In .NET, there are so many types that I seem to spend more time hunting around in msdn for a class than writing code. It also interrupts my workflow while I'm working because I have to type a little bit than look something up.

Obviously, I don't have to do this for the basic classes. Whenever new things come though there is definitely some looking up to do. Then I often don't reuse that class enough to really review it or bring it into action.

I'm wondering if anybody out there has a found a way to memorize (or look up more efficiently) these object model hierarchies?
