Developers can use any .NET Language The .NET Framework provides a foundation of
classes for developers to build a wide variety of applications
Source code is compiled to MSIL within an Assembly
Assembles contain rich meta data and are the primary units of deployment
MSIL is compiled to native code and executed by the Common Language Runtime
