Building .NET 3.5 CF app for MC32N0 and MC92N0



I have a .NET 3.5 CF application which needs to run on both MC32N0 and MC92N0 devices.


It will run on both of them correctly - however I can't seem to do one build within Visual Studio so that the built app will work on both. I have to specifically set the target device to each one and do a build each time (I have both PSDK installed). I am using EMDK 2.8.


Can anyone point out the likely obvious mistake I am making?
