VB and C# together share about 50% of the “garbage-collected languages” market. How do Microsoft design these languages? Where do they get ideas? How do they incorporate new paradigms without breaking the existing languages? Where will they go in the future and how will we get there?

C# (C Sharp)is a type-safe object-oriented language created by Microsoft that enables developers to build applications that run on the .NET Framework. This video presents the basic concept behind the C#.

Do you think about software design? Do you want to know what those fancy acronyms mean? Do you kind of know what they mean but want to see the concepts in flesh and bone? I you answered yes to any of the questions, you might not get bored in this session when we talk about the good, bad and the ugly from those principles and show C# code to exemplify the concepts.
