Is it possible to run Silverlight 5 RC application that is using P/Invoke to access Win API functions while the application is run in web browser? The source of the application is from web site on internet.
I am asking this because I have no luck.
I am experiencing Error: Unhandled Error in Silverlight Application Attempt by security transparent method ‘xxxx’ to call native code through method ‘yyyyy’ failed.
Methods must be security critical or security-safe-crictical to call native code.
I tried adding [SecurityCritical] attribute on the method calling the P/Invoke method but with no success. Then I tried to put it to the entire calling class but again with no luck.
Does anybody has a solution for this?
Is it possible to do that ?
Is it a problem because of the partial trust of applications from internet ?
To use P/Invoke, your SL application must be a full-trust application.
You can run trusted application from a browser, but it requires some setup by an admin.
