Generics came on the scene in .NET 2.0 and have been a mainstay ever since! I have developed numerous application frameworks over the years and in every case I have made full use of generics. Very similar to templates in C++, generics allow dynamic type-based operations in a strongly-typed manner and can provide build-time validation. Generics allow us define classes and methods without committing to specific types while we are coding. I am not going to go into a discussion of generics in a general sense since this MSDN resource does a pretty good job of providing a description.
