 # Introduction to the C# Language and the .NET Framework
 C# is an elegant and type-safe object-oriented language that enables developers to build a variety of secure and robust applications that run on the [!INCLUDE[dnprdnshort](~/includes/dnprdnshort-md.md)]. You can use C# to create Windows client applications, XML Web services, distributed components, client-server applications, database applications, and much, much more. Visual C# provides an advanced code editor, convenient user interface designers, integrated debugger, and many other tools to make it easier to develop applications based on the C# language and the [!INCLUDE[dnprdnshort](~/includes/dnprdnshort-md.md)].
