Silverlight 4 - High Resolution * Inside * Browser

Question

I know that Silverlight 4 can handle elevated permissions outside of the browser. Is there any way to execute this inside the browser?

I need to create a folder / file download manager that gives a better user interface than the standard, and I would like to implement it in Silverlight.

I know that Java has the ability to receive elevated permissions, but you need to attach a signed certificate to your application. Does Silverlight 4 have a similar option - get elevated permissions by adding a signed certificate (of course, after a user’s warning)?

Answer 1

I believe that the full trust option is only available as an OOB application - ref: http://timheuer.com/blog/archive/2009/11/18/whats-new-in-silverlight-4-complete-guide-new-features .aspx # elevated

Answer 2

This is possible in Silverlight 5, but this requires the registry key 'AllowElevatedTrustAppsInBrowser'. See: How to enable trusted applications to run inside the browser

This makes this function almost useless: the installer should not change the key, because it is a global value for all applications, so only local intranet applications can benefit (where server policies can change this key).

If I'm wrong, please correct me, because it would be great to trust applications in the browser :)
