When I build my Silverlight Xap I need to create it as an in-browser trusted application which runs with elevated trust. To achieve this I have to sign the manifest with a valid security certificate which I purchased from Comodo.

When my Silverlight Xap runs, it needs this elevated trust to be able to communicate via HTTP with other websites.

Can you provide this feature in C#/XAML?

I am happy to discuss funding this requirement with you if you consider it too specialized.
