according to the documentation about interfaces it's seems impossible to accomblish this. So I'm wondering if there is some way around this "limitation"?

It depends on what you want to do. You can create an abstract class, make all its members abstract and then inherit from it (instead of implementing the interface). Then you can write a static method with its implementation in the abstract class or you can try to create an instance of the inheriting class and call its method. But then you should know the inheriting class which is probably not your case. This solution can probably hide from the outside world that the method is not actually static, but in reality the working method cannot be static.

Yes i could do that but I want to make it userfriendly. I also want it to be easy to implement more different interfaces with static members, so a abstract class will not work in my case. Right now I'm using the Type.GetMethod() with bindingFlag static to determine wheter the static method is implemented or not.
In my case there is a bunch of dll:s located in directory and I want to be able to determine what object that should be created, based on the return value of a static method on all classes that implements a specific interface.

You can check whether the class implements the intefrace and if yes, use the method you already do use: the GetMethod() and then call it. Unfortunately there is no way to make static members abstract or virtual or members of an interface :-((
