I'm getting push back on a design from a colleague, and am wondering if there's consensus as to who is correct on application of SRP in this case. I see SRP as relating mostly to the lower-level details of design, such as class responsibility. As you move up in levels of abstraction I believe SRP is still relevant but that the definiti...

Hi guys, Look at here (Abstract Class Design): http://msdn.microsoft.com/en-us/library/ms229047.aspx It says: (1) Do not define public or protected internal (Protected Friend in Visual Basic) constructors in abstract types. In C#, we are not able to instantiate an abstract class. So, does it still matter to define public constructors...
