.Net Technology – In a Nut Shell

CTS and CLS

• CTS: The common type system is a rich type system, built into the common language runtime, that supports the types and operations found in most programming languages.
  
• CLS: The common Language Specification is a set of constructs and constraints that serves as a guide for library writers and compiler writers. It allows libraries to be fully usable from any language supporting the CLS and for those languages to integrate with each other. It is a sub set of the CTS.
  

Deploying .NET Applications

• The .Net Framework simplifies deployment by making zero-impact install and XCOPY deployment of applications feasible.
  
  
• Code download support offers incremental download, code access security and application isolation.
  
  
• The windows Installer is another powerful deployment mechanism, including publishing, advertisement, and application repair available in 2.0.

Framework Class Library

.NET Framework Class Library (FCL)

• provides the fundamental building blocks for any application
