Can I just add that the CLR also caters for protected AND internal access but (apart from reflection emit) this is not supported by either C# or VB.NET. I believe there were two reasons for this: 1. The language designers didn't think it would be used much, if at all. 2. They couldn't think of a suitable name for it anyway :) However, it is supported in C++/CLI ( as 'protected private') for anyone who uses that language.

Internal- You can access withing that assembly. Protected- you can access it in child classes. So protected internal will be a combination of both. You can access within the same assembly as well as child classes present inside other assembly. Let me tell you smalll example. I have assembly1, assembly2 In assembly1 i have a parent Class Vehicle. In the same assembly i have a class Car derived from vehicle. Now in assembly2 , i have class Bus derived from vehicle(Assembly1). Now if i have 2 methods CalculateMileage, GetFuelCapacity Calculate Mileage i declared it as internal access specifier and GetFuelCapacity i declared it as protectedinternal. Now when i check the methods for Bus, i can see only GetFuelCapacity, thats because its declared as protected internal. Hope this would help you to understand well..
