What is.net.net is a comprehensive family of products, built on industry and Internet standards, that provide for each aspect of developing (tools), managing (servers), using (building block services and smart clients) and experiencing (rich user experiences) XML Web services.

.net offers language independence. Code written in VB.Net, C++ and C# by MS Python, Cobol, Perl etc by third party vendors. Translated into MIL (MS Intermediate Language). Something analogous to Java Byte Code. MIL code can be interpreted by CLR (Common Language Runtime Environment). Sort of JRE (Java Runtime Environment)

.net Framework.NET Framework is an "environment for building, deploying and running Web services Three main parts – Common Language Runtime (CLR) – Framework classes – ASP.net

A Perspective “ Microsoft.Net can be summarized in one simple statement: Microsoft is building an Internet Monopoly ” Gary Hein Tech News: August 29 th, 2001

.net Pros Multiple Language Support. Rich set of libraries. It's open-standard friendly (e.g., HTTP and XML) Its code is compiled natively, regardless of language or deployment (Web or desktop).

.net Cons It's yet another platform to consider, which generally means rewriting and learning new tricks. Currently, it's only available on Windows. Microsoft claims C#, IL, and CLR/CLS will be submitted to ECMA, but there's still no clear view on what will be standardized from the platform.
