I am running OOB silverlight application where I have a WebBrowser control but I am getting this error when I call InvokeScript:-
Attempted to perform an unauthorized operation.
Is it because it's OOB ?

A:
No it can't be because its OOB since WebBrowser only works OOB anyway. I can think of two possible reasons.
The Url to which the WebBrowser has navigated is not on the same site from with the Silverlight application has been loaded. This would a security violation.
The code that is being executed in the loaded web page by the
InvokeScriptis the actual source of the error.

@Miroo: Yes that is exacly what I'm saying. You cannot call JS functions in a page that comes from a different site than you Silverlight application. This would constitute a cross-domain scripting breach which could endanger the users privacy or worse their bank account.

@Miroo: EnableHTMLAccess is placed on the object tag when a silverlight application is embedded in a web page, it isn't relevant to your case. An OOB runs "out of browser" so clearly it isn't going to debug through the web page.
