Java developers—learn C# quickly and thoroughly with this book!

Although Java and C# share many similarities, there are fundamental differences between

them. What's more, C#—the language designed from the ground up for programming

the Microsoft® .NET Framework—offers a wealth of new features that enable programmers

to tap the full power of .NET. This is the ideal guide to help any experts—reveal

the similarities and differences between the two platforms these languages support. Then they

show you how to leverage your Java experience to get up to speed in C# development with

a minimum of difficulty. It's the definitive programming resource as you tackle the .NET class

libraries and learn to write applications for .NET with C#.
