With normal .net applications in the properties window you can change the .net framework of your application from 3.5 to 2.0.
I’m looking for something like that for a pocket pc application, because I get an error on my pocket pc that my app requires a newer version of .net. and I can’t find it anywhere in the properties.
First – you might want to check the ‘Devices’ tab (VS2008), and check the ‘Deploy the latest version…’ box (to push 3.5 onto the device, if this is an option).
It is entirely possible that you need to re-create the project file to do change the target to 2.0 (i.e. create a new project, selecting 2.0 on the first screen). It usually isn’t a big job to copy in the .cs files etc…
If the project is large, you might consider editing the csproj manually, but I’m not sure I’d bother… probably less work to just re-add the code.
