Questions every good NET developer should be able to answer

0 votes
My company is in the process of hiring.NET professionals. We deal with ASP.NET, Compact Framework, Windowsforms, and Web Services, among other.NET platforms. I'd like to put together a list/catalog of useful questions as a type of minimal criteria for determining whether or not the applicants have prior experience. So, here's my question:

What questions do you believe a good.NET programmer should be able to answer?

I'd also use it as a self-checklist to evaluate where my own deficiencies are (I have many!)

If I were interviewing someone who knew LINQ, I'd probably just ask them to explain it to me. They should be able to describe deferred execution, streaming, the IEnumerable/IEnumerator interfaces, foreach, iterator blocks, and expression trees (at least for extra points). (I'm thinking of the instance where they've claimed to know enough LINQ to make it a legitimate inquiry - admittedly, they could be "decent" developers and not "understand" LINQ yet.)

I've previously asked several of the questions listed above, as well as a few others:

  • Difference between reference and value types
  • Delegates
  • Strings, immutability, character encodings
  • Pass by reference vs pass by value
  • IDisposable and finalizers
  • Nullable types
  • Floating point
  • Generics
