Doru-

>I'm trying to read (then write to, if I could read first...) an XML in a simple SDE form. When running the emulator I get the unhandled exception error filenotfound... I've put the .xml/.xsd files in the same dir with the app, or under bin directory, I even included them in the project. Nothing helps...

I expect this is too obvious to be possibly correct, but does the AppDomain class help you? For example, AppDomain.BaseDirectory?
