Extension methods (part 1)

But this will only cover extension methods that are already pulled into scope, right? It would be helpful to be able to discover extension methods whose namespaces haven't been imported. This would be similar behavior to the rather-useful feature that discovers namespaces for types and offers to import or prepend them.

"It would be helpful to be able to discover extension methods whose namespaces haven't been imported."

That would clutter up intellisense. I don't want to be bothered with details about a namespace i didn't import.

kfarmer,

Thanks for the feature idea. I can't guarantee that we will be able to include your feature in Orcas, but I will forward your request over to the UI team for consieration in a future version of the product.

One things to consider is that although extension methods are only visible if they are in scope, if you define an extension method in a module in the top level namespace of your of your project (or solution), then you can use these extension methods without having to explictly import them in every file in your project. This won't help with discoverability of extension methods written by third party class library authors, but it will help with extension methods that you or other people on your projects write.

Will it be ever possible to replace not-virtual private and protected methods/properties in compiled assemblies? Thanks.

Hex,

Thank you for your suggestion. At the momenet we have no plans to support allowing extension methods to override eixsting instance methods. In fact the feature is specifically designed to not allow extension methods to replace the definition of instance methods (instance methods hide extension methods by name, so an extension mehtod can never be called if an instance method with the same name exists on the class). Hower, I will forward your suggestion over to our langauge design team so that they can consider it for a future version of the product.

Thanks,

-Scott

Just build your module in a class library, and a .dll is EXACTLY what you'll make.
