Security Exception - mscorlib, Retrieving COM class component with CLSID failed

Question

I have having trouble in this phase where it initialize the app.

public static void Initialise()
    {
        Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); //throwing exception here
        Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
        AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
    }

I have web config where

<trust level="full"/>

Message is:

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I was struggling a lot on passing this security exception. Read loads of blogs, involved in discussions but nothing worked out.

Finally found 'Enable ClickOnce Security Settings' in msdn. I just followed those steps and disabled the Security Setting in Project properties.

Here is a link hope this helps some: http://msdn.microsoft.com/en-us/library/1sfbfyk0.aspx
