InterfaceFactory Authorization

[keithdv]

Difficult because the developer is defining the interface so changing the signature to Authorize<> and adding the CanXYZ methods is not a given.

Ideas:

If the interface is partial then add the methods.
If the server implementation for the interface is partial add them there as well.

Or

Create an entirely new interface IInterfaceAuth that has the methods

[keithdv]

Or I think the best idea

Inherit from the provided type and add the CanXYZ methods

public interface IExecuteMethods {

    [AspAuthorize()] // Or AuthorizeFactory on the Interface
    Task<int> MyMethod(string a, string b);

    [AspAuthorize()] // Or AuthorizeFactory on the Interface
    Task<string> AnotherMethod(string a, string b);
}

Neatoo generates:

public interface IExecuteMethodsFactory : IExecuteMethods {
    Task<bool> CanMyMethod();
    Task<bool> CanAnotherMethod();
}

Duplicate method names could not be allowed.
