NET Framework (pronounced as "dot net") is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library named as Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (in contrast to a hardware environment) named the Common Language Runtime (CLR). The CLR is an application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called "managed code". FCL and CLR together constitute the .NET Framework.
The .NET Framework version 1.1 redistributable package includes everything you need to run applications developed using the .NET Framework.
The .NET Framework version 1.1 provides improved scalability and performance, support for mobile device development with ASP.NET mobile controls (formerly the Microsoft Mobile Internet Toolkit), support for Internet Protocol version 6, and ADO.NET classes for native communication with Open Database Connectivity (ODBC) and Oracle databases. It also enables the use of code access security to further lock down and isolate ASP.NET applications. For more information, read the .NET Framework Version 1.1 Product Overview.
Important: You cannot install two different language versions of the .NET Framework on the same machine. Attempting to install a second language version of the .NET Framework will cause the following error to appear: "Setup cannot install Microsoft .NET Framework because another version of the product is already installed." If you are targeting a non-English platform or if you wish to view .NET Framework resources in a different language, you must download the appropriate language version of the .NET Framework language pack.
