Interface -- C# thing or .NET thing

[gz]

Hi All,

I am wondering if the notion of interface is a C# thing or .NET thing.
In other words, is it supported at the language level, like C++'s
support of classes, or at the runtime level? Could anyone help?

Thanks,
gz

It's an OO thing. Object Oriented.

Well interfaces are defined ALL over the framework. That only should
indicate that they are a .NET "thing" don't you think?

The .NET runtime enforces the restriction of multiple inheritance to
interfaces.

Interfaces are an integral part of the common type system and so is
defined at level even lower than the runtime. Read the Common
Language Infrastructure specification (ECMA-335) for more information.
