How to override explicit interface members

[curt-w]

I'm trying to understand how to override properties / methods that are explicitly defined within an interface. I'm running into issue with this more complex situation

Provided the following model, how would I write an aspect that is capable of overriding the property getter that is explicitly defined under InterfaceB. For example purposes, let's ".ToUpper()" the result using a ProjectFabric. I haven't had issue targeting the types via. the fabric layer, just having success in the aspect actually being able to manipulate the explicitly defined member within the implemented interface.

public interface InterfaceA
{
    string TestStringProperty { get; }
}

public interface InterfaceB : InterfaceA
{
    string InterfaceA.TestStringProperty { get => "base_impl"; }
    string TestStringPropertyLocal { get; }
}

public class TestClass : InterfaceB
{
    
    public string TestStringPropertyLocal { get { return "local_impl"; }}

}

Overriding of default interface member implementation is not supported at the moment.

Thanks - is there a feature request for tracking?

My intent with this approach was so my source code would be cognisant that these properties / methods exist and refer to them throughout, while I can worry about the actual implementation within the AOP layer. Not sure if you have any ideas on an alternate solution.

We have filed this feature internally and it is planned to be implemented. We'll let you know as soon as it's released.

We don't see any alternative approach at the moment.

The user story has now been implemented.
