The Microsoft .NET Compact Framework 2.0 Beta 2 Redistributable includes everything you need to run .NET Compact Framework applications, including the Common Language Runtime and the .NET Compact Framework class library.
Important: This package uses ActiveSync to update the device. Make sure to dock your device before running NETCFSetupv2.msi. You can run the ActiveSync setup later by going to your install folder and running NETCFSetupv2.msi once the device is docked. Those not using ActiveSync can run the CAB files which match the device found in the install folder directly on the device.
