Develop a software in C#

Although I have been a C# MVP for 4 years in a row, there were not many softwares that I developed in C#. Anyway, about a month ago, I just started a new software project. Not big project. This time I make my mind to give it a try in C#, and I've finished most of the requirements in the project.
I wrote a C# book 7 years ago. At that time C# Beta 1 was just released, and I, of course, wrote it based on C# Beta 1. I have been translated many technical books for 7 years. It's already 10 books. So, I am a professional C# software engineer? I don't think so. We can learn only from project, not in a book. I have been thinking all I need to do is more projects. Not any more books!

I am so happy in these days because I do the project in C#. :-) I really love .NET and C#
