1) .NET is Microsoft’s new strategy for the development and deployment of software.
2) .NET fundamentally changes the way applications execute under the Windows Operating System.
3) .NET brings about significant changes to both C++ and Visual Basic, and introduces a new language called C# (pronounced “C sharp”).
4) .NET is built from the ground up with the Internet in mind, embracing open Internet standards such as XML and HTTP. XML is also used throughout the framework as both a messaging instrument and for configuration files.
