Overview

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.

Additional information

Server Installation Requirements
If you have been directed to do a server installation, you must have the following software installed in addition to the typical installation requirements:

  • Microsoft Data Access Components 2.6; Microsoft Data Access Components 2.7 SP1 is recommended. This is for applications that use data access.
  • Internet Information Services (IIS) version 5.0 or later. To access the features of ASP.NET, IIS with the latest security updates must be installed prior to installing the .NET Framework.
  • ASP.NET is supported only on the following platforms: Microsoft Windows 2000 Professional (Service Pack 3 recommended), Microsoft Windows 2000 Server (Service Pack 3 recommended), Microsoft Windows XP Professional, and Microsoft Windows Server 2003 family.

Note: Most users will perform a typical installation and can ignore these requirements. If you are unsure which type of installation to perform, meet only the typical installation requirements.

If you plan to develop .NET Framework version 1.1 applications, the Microsoft .NET Framework version 1.1 Software Development Kit (SDK) includes everything you need to write, build, test, and deploy .NET Framework applications—documentation, samples, and command-line tools and compilers.

Microsoft .NET Framework 4 (Web Installer)

The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.

The .NET Framework 4 works side by side with older Framework versions. Applications that are based on earlier versions of the Framework will continue to run on the version targeted by default.

The Microsoft .NET Framework 4 provides the following new features and improvements:

  • Improvements in Common Language Runtime (CLR) and Base Class Library (BCL)
    • Performance improvement including better multicore support, background garbage collection, and profiler attach on server.
    • New memory mapped file and numeric types.
    • Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.
    • For a comprehensive list of enhancements to CLR and BCL go here.
  • Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
  • Improvements in Data Access and Modeling
    • The Entity Framework enables developers to program against relational databases using .NET objects and Language Integrated Query (LINQ). It has many new features, including persistence ignorance and POCO support, foreign key associations, lazy loading, test-driven development support, functions in the model, and new LINQ operators. Additional features include better n-tier support with self-tracking entities, customizable code generation using T4 templates, model first development, an improved designer experience, better performance, and pluralization of entity sets. For more information go here.
    • WCF Data Services is a component of the .NET Framework that enables you to create REST-based services and applications that use the Open Data Protocol (OData) to expose and consume data over the Web. WCF Data Services has many new features, including enhanced BLOB support, data binding, row count, feed customization, projections, and request pipeline improvements. Built-in integration with Microsoft Office 2010 now makes it possible to expose Microsoft Office SharePoint Server data as an OData feed and access that data feed by using the WCF Data Services client library. For more information go here.
  • Enhancements to ASP.NET
    • More control over HTML, element IDs and custom CSS that make it much easier to create standards-compliant and SEO-friendly web forms.
    • New dynamic data features including new query filters, entity templates, richer support for Entity Framework 4, and validation and templating features that can be easily applied to existing web forms.
    • Web forms support for new AJAX library improvements including built-in support for content delivery networks (CDNs).
    • For a comprehensive list of enhancements to ASP.NET go here.
  • Improvements in Windows Presentation Foundation (WPF)
    • Added support for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
    • Added support for Surface 2.0 SDK.
    • New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.
    • Improvements in performance and scalability.
    • Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.
    • For a comprehensive list of enhancements to WPF go here.
  • Improvements to Windows Workflow (WF) that enable developers to better host and interact with workflows. These include an improved activity programming model, an improved designer experience, a new flowchart modeling style, an expanded activity palette, workflow-rules integration, and new message correlation features. The .NET Framework 4 also offers significant performance gains for WF-based workflows. For a comprehensive list of enhancements to WF go here.
  • Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support. Additionally, .NET Framework 4 provides new WCF features such as service discovery, routing service, REST support, diagnostics, and performance. For a comprehensive list of enhancements to WCF go here.
  • Innovative new parallel-programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors.

What happens if I don't install the Microsoft Download Manager?

Generally, a download manager enables downloading of large files or multiples files in one session. Many web browsers, such as Internet Explorer 9, include a download manager. There are many stand-alone download managers available as well, including the Microsoft Download Manager.

However, if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

  • You may not be able to download multiple files at the same time. In this case, you will have to download the files individually from the "Thank you for downloading" page.
  • Files larger than 1 GB may take much longer to download and might not download correctly.
  • You might not be able to pause the active downloads or resume downloads that have failed.
  • Files may be more difficult to download or take longer to download.
