Have read introduction level guides of C#. Not a serious developer. Just have a fun with it. Interested in VSTO. Banned from local C# community called "Hoons dot net" becaus I have posted some fundamental questions, such as, what is the difference between classes and types. (In my opinion, it's full of real idiots. In Korean, "덜 떨어진 병진 새뀌덜-특히, 박경훈 지진아 새뀌").
