Quick information on Generics


Update Jan 7, 2005: Generics will be CLS Compliant!

I’ve recently received a couple of questions on how generics will be supported across languages so I thought I would point out Julie Lerman’s blog entry on the subject of C#, VB, and J# support for generics.  C++ will have both templates that are available today and generics.  You can find out more information about the differences between C++ templates and generics at the C# FAQ blog and on Brandon Bray’s post on the subject.

Other things to note: Generics are not CLS compliant in the .NET Framework 2.0, but will be for Longhorn.

    Ugh. How come generics are not be CLS compliant?

  2. Hey Ron, I’m tracking down an official answer now….

  3. Peter Drayton, a PM on the CLR team provides the following explanation:

    "CLS consumption defines a minimum bar that all languages targeting the CLR must meet if they wish to be able to consume the breadth of .NET Framework APIs. Adding a feature such as generics to the CLS requires all the languages running on .NET (currently, about 30) to be updated to consume generics. This can be a significant change for some languages, and we felt that the best way to introduce this to our language partner ecosystem would be in a staged fashion: generics available in Whidbey, and CLS compliant in Orcas."
