Not that easy Einar, what you or the other developers need to do is create a CF class project assuming that your classes are on a class project, then add your cs files to the project and build a CF assembly, then that assembly can be used on any CF projects.

>Thanks for the reply. Yes I just noticed that CF2.0 has some of the crypto stuff. I don't acctually do the PDA programming myself, I only do PC stuff but I write classes that I share with the PDA guys, and that is why I don't keep up on CF as much as I should <s>.

>>>The compact framework does not contain (hardly) any crypto stuff (System.Security.Cryptography). I have been using a class I wrote to encrypt and decrypt text (which used a lot of stuff from System.Security.Cryptography). Now I need to share my encrypting and decrypting with a PPC application and since a lot of this is not available in the compact framework I either have to write my own or use someone elses.
