Do you declare member accessibility for all classes?

Not explicitly specifying the access type for members of a structure or class can be misleading for other developers. The default member accessibility level for classes and structs in Visual C# .NET is always private. In Visual Basic .NET, the default for classes is private, but for structs is public.
