The Microsoft .NET Compact Framework 3.5 Beta1 testing Redistributable contains the common language runtime and class libraries built for the .NET Compact Framework. In addition to supporting version 3.5 beta1, it also supports applications developed for version 2.0 and 1.0. Important: This redistributable enables running .NET Compact Framework applications on the Pocket PC, Pocket PC Phone Edition, Smartphone, and other Windows CE powered devices. To develop .NET Compact Framework 3.5 Beta1 applications, Microsoft Visual Studio Orcas Beta1 is required. This package uses ActiveSync 4.0 and up to update the device, see the Windows Mobile Center for more information. Be sure to dock your device first before running NETCFSetupv35.msi. If your device is not docked, ActiveSync will store the CAB file until the time when you dock your device. Those not using ActiveSync can run the CAB files which match the device found in the install folder directly on the device.
