Although CSharp is derived from the C programming language, it has features such as garbage collection that allow beginners to become proficient in CSharp more quickly than in C or C++ . Similar to Java, it is object-oriented, comes with an extensive class library, and supports exception handling, multiple types of polymorphism, and separation of interfaces from implementations. Those features, combined with its powerful development tools, multi-platform support, and generics, make CSharp a good choice for many types of software development projects: rapid application development projects, projects implemented by individuals or large or small teams, Internet applications, and projects with strict reliability requirements. Testing frameworks such as NUnit make CSharp a menable to test-driven development and thus a good language for use with Extreme Programming(XP). Its strong typing helps to prevent many programming errors that are common in weakly typed languages.
