I am working on a fairly large solution(24 Projects altogether, C#). 

So far I have been testing the application only in browser, where it all works fine. 

I have now tried to run it OOB (from within VisualStudio 2010). The application starts but then just hangs. I can see that it stops working the fist time it tries to get data from the Server. 

I have no idea of what to do to find the error. 

I have created a simple DevForce application that reads from the NorthwindIB Database and this one works fine out of browser. I then compared the properties of the the two solutions they are identical (Port 9009 etc.)

Can you give me some ideas about where to look next?

Thank you 

Markus Seeli

I managed to get an exception after a couple of minutes of waiting. (Sorry for the German, but it should be readable)

I checked the server is running at:

http://localhost:9009/EntityService.svc

I start the application, the oob-windows opens and is empty and stays empty.  - when i then click on the development server in the system tray and tell it to open in browser the application opens in a browser and works fine.

I found the problem:

I am using Caliburn and Caliburn initializes the rootview after it has done the entire MEF initialization. I was trying to access my database before the rootview was set and somehow DevForce does not like this. 

This problem only shows up in OOB-Mode, within the browser the late init of the rootview is not a problem.

I solved the problem by showing a splash-screen before I access the db via DevForce.

Thanks for the update mseeli,
 
At first we suspected it could be the OOB app hanging when trying to make a connection to a secure WCF, but I couldn't reproduce it here.
 
I was about to check if it had anything to do with SL5 Beta being installed on the machine, but you saved me that trip.
Silvio.
