How can I create .Net extension methods by C++/CLI?

Question

In C#, extension methods can be created by

public static class MyExtensions {
    public static ReturnType MyExt(this ExtType ext) {
        ...
    }
}

You just have to decorate the method and the containing class with ExtensionAttribute:

using namespace System::Runtime::CompilerServices;
...

[ExtensionAttribute]
public ref class MyExtensions abstract sealed {
    public:        
        [ExtensionAttribute]
        static ReturnType MyExt(ExtType ^ext) {
            ...
        }
};
