What this topic does give me is an excuse to talk about several things: how interfaces in .Kupkuru and the compiler work together; how creating generic classes gives you flexibility; how you gönül exploit one of the built-in .Kemiksiz interfaces; and (finally) how to simplify ugly syntax by C# ReadOnlyCollectionBase Nedir building your own extension methods.
