Hi Paul,

yes you have much more flexibility but the problem is that you will need to sign your binaries with an official certificate (you can get these for example at verisign). If you do this you will have full access to everything.

Hello Daniel,

Is there some more flexibility in using WCF via a full-trust XBAP?
Or do the BasicHttpBinding & the site-of-origin restrictions still apply?

Regards,
Paul

Hi Daniel, I tried doing all this, i followed all the steps you mentioned here but i am unable to run XBAP with WCF in partial trust environment. I keep getting “An error occurred creating the configuration section handler for system.serviceModel/bindings: That assembly does not allow partially trusted callers. (C:\Documents and Settings\adityak\Local Settings\Apps\2.0\BKBGN6JY.XYQ\L4YWNGV0.POH\xbap..xbap_f2981c3a40e6c63b_0001.0000_3aec96efea0ef260\XbapApplication.exe.config line 4) —> System.Security.SecurityException: That assembly does not allow partially trusted callers.
”

this error. Please help me, i am struggling for this for long time now.

Thanks,

Aditya

Hy Gianni,

I assume, you start debugging the xbap application by hitting F5 or clicking in the context menu of the project “Debug->Start new process”. But this will only attach the debugger to the xbap application not to the wcf service application. You have two possiblities:

- Start debugging the xbap. Before using any wcf function go back to Visual Studio. Open the Debug menu and klick “Attach to process”. Choose either the aspnet_wp.exe or w3wp.exe if you are using the IIS for hosting the wcf service. If you are using the asp.net developer webserver, choose the process for the development webserver. Then click “Attach”. Now you are debugging xbap and wcf host at the same time and should be able to step into the service function.

- Second possiblity is to tell visual studio to start both applications when hitting F5. For this you have to right-click on the solution in the vs solution explorer. Choose the “Set startup projects” item. On the right pane, select “Multiple startup projects”. Activate all projects, which you want to debug at the same time in the right column. After clicking “ok” you can hit F5 to start all selected projects.

Regards

Hi Gianni,

did you set the debug settings in the xbap project to use the presentationhost.exe as startup program? If not, try the settings from the above post to do the debugging. If this does not help, please contact me again.
