2. Added generate cert script to project files. 3. Made "\\" platform independent, even for .Net4 samples (apart from GDS samples). 4. Fixed cert validation popups (yes/no was reversed!). 5. Got GDS server and client samples running (no connection yet). 6. Fixed configuration and popups in GDS client.
