Every once in a while, I get asked if I have any suggestions as to how to get started with .NET/C# development. Generally, the person asking has a good background in programming and design. In order to really use a language and library, though, you want to know which concepts and patterns are used in a language as well as what those patterns are called, how to use them and so on. If you don’t know what’s already available, you end up reinventing the wheel or doing things in an inefficient way.
Generally, you can find information about many of these topics at Microsoft’s MSDN documentation or you can search for articles on working with them. Just remember to always look for existing functionality in the .NET framework or the Quino framework—only if you have the pleasure of working with it, naturally—or by searching for solutions online. A good place to look for such solutions is Stack Overflow.
