C #: Folder structure with service level, interfaces and layouts?

Question

I recently started creating service layers and made announcements like:

MyService myService = new MyService(); myService.DoSomething(); 

This was inspired by some ASP.NET MVC videos, and I like the template.

Then I started creating interfaces and mocks like:

 IMyService myService = new MockMyService(); myService.DoSomething(); 

Therefore, I can isolate parts of the code for testing. But now my service level folder is loaded with classes, interfaces and layouts:

 IServiceTypeA.cs ServiceTypeA.cs MockServiceTypeA.cs IServiceTypeB.cs ServiceTypeB.cs MockServiceTypeB.cs ... IServiceTypeZ.cs ServiceTypeZ.cs MockServiceTypeZ.cs 

How do you arrange them logically?

Answer 1

 - Providers ServiceTypeA.cs ServiceTypeB.cs ServiceTypeC.cs - Interfaces IServiceTypeA.cs IServiceTypeB.cs IServiceTypeC.cs - Testing - Unit Tests - Mocks MockServiceTypeA.cs MockServiceTypeB.cs MockServiceTypeC.cs 

Or you can use the Mocking frameworks to create the mock services generated at runtime.
