The Microsoft .NET Framework version 1.1 Beta extends the .NET Framework version 1.0 with new features, improvements to existing features, and enhancements to the documentation. The major feature areas of this new release are outlined in this overview document.
Native Support for Developing Mobile Web Applications
The .NET Framework 1.1 Beta now features native support for developing mobile Web applications. ASP.NET Mobile Controls (formerly the Microsoft Mobile Internet Toolkit) extend ASP.NET server controls such that they adapt to the mobile device on which the Web application is rendering. Through browser detection, the mobile controls conform to the capabilities of individual devices ranging from full-featured personal digital assistant (PDA) browsers to small, 5-line Ã— 20-character mobile phone displays. This adaptive rendering feature handles many of the tedious, device-specific rendering decisions and frees you to focus on your Web application logic. The .NET Framework 1.1 Beta incorporates the mobile controls into the .NET Framework and Microsoft Visual Studio® .NET distributions.
