System.Security.SecurityException: That assembly does not allow partially trusted callers.

any idea? tanx

Answer 1

Reza, make sure the AutoCompleteBox assembly supports partially trusted caller. This is usually done through [AllowPartiallyTrustedCaller] attribute definition on the source assembly.

If you don't have access to the source file in order to add the attribute, you can change your application to run full-trust.

Hope this helps.

This problem solved in Visual Studio 2010 and can use it without any exception
