What's the best way to get the CF 2.0 runtime onto the remote device if the CF 1.0 runtime is already installed?

There are two ways to get NETCF on CE 5.0:

*CAB installation, NETCF in RAM
*Platform Builder QFE, NETCF in ROM.

CF 1.0 and CF 2.0 can run side by side. That means CF 1.0 removal is not required. In that case 1.0 applications would run against CF 1.0 and 2.0 applications against CF 2.0.

Configuration file can be used to force 1.0 apps to run using 2.0 runtime. To do this do the following
*Create a configuration file using the same naming convention as the full .NET Framework (Myapp.exe.config)
*Add the following to the config file

		 <configuration> 
		  <startup> 
		    <supportedRuntime version="v2.0.5238"/> 
		  </startup> 
		 </configuration> 
	

*Copy the file to the device in the same folder as the application (\Program Files\Myapp)

If CF 1.0 is removed, 1.0 applications will automatically run against CF 2.0 providing significant performance benefits.
