Multiple Device Manufacturer Portability Advise

Question

I am new to C# and .Net CF programming.

I want to be able to develop a single application that I can deploy to multiple devices.  For instance, I want to deploy the same application to a Symbol, Intermec, Motorola, and Unitech devices.  

My project will have references to all of the different device SDK's and specific #if else statements to handle the different devices.

However, I'm not sure how to have C# code identify the type of device and then to somehow make that device type available for the rest of the code to decide which SDK api's & associated variables to use.

Also, I only want to have a single application to do this.  I realize I could create a single cab file for each separate device, but that's not what I'm looking for.  I really want one application, with a single executible that figures out the device it's running on and handles the specific SDK calls.


Any help will be greatly appreciated.

Thanks,

Steve
