Something has changed from C# 1.0 to 2.0 regarding interface
re-implementation. See my sample code below; when compiled and run under VS
2003, you get:
Control.Paint
Control.IContro l.Paint
But when compiled and run under VS 2005: you get:
Control.Paint
Control.Paint
Please explain why in C# 2.0, a class that re-implements an interface
prefers to map to a virtual method of the base class rather than an explicit
implementation of the base class.
Thanks
