New WPF Features: Full Trust Xbap Deployment

  • Article

This is part of a series on New WPF Features 

In earlier versions, on trying to deploy a Full Trust Xbap, you would get a "Trust Not Granted" error. Its possible to workaround this issue by installing an assembly in the GAC that has the AllowPartiallyTrustedCallersAttribute. Another option is to install a certificate on the user machine and sign the Xbap with the certificate. Yeah, its painful and we worked on this issue for this release

Now on deployment, you would get a clickonce dialog so that the user can determine if s\he want to run the Xbap. This is really beneficial in the case of Intranet deployment. Do I hear a WOW.. :)

Below is the pictorial difference..

 

In addition, clicking on the More Information link open up a dialog with additional information that would enable the user to make a more knowledgeable decision about installation

    Great. This is good feature.. We ended up having the certification when we were developing full-trust xbap app.

    This is one pain that I have to deal with XBAPs before. Even if I set the project to full-trust settings, it still won't run when the application is deployed. Gotta have to try this one when I reach home. Great job guys!

    Once you click to allow it to be run the first time, will the user continue to see the same security prompt each time they return?  Thanks!

    As long as there are no updates to the app, the user wouldnt be shown the security prompt the second time.
