For a .NET developer interview, what are the main technical questions

Question

I consider myself a fairly competent self-taught programmer. I am very strong in applying concepts, even though I have no formal education with it. However, Most of my interviews have fallen flat due to an inability to recall certain principles of programming (for example, I can never remember the L in SOLID). Some questions, I am not even sure how to describe the principles, even though I use them daily. What are some of the questions I should be prepared for in a usual .NET technical interview?
