I’m binding a third party(red park sdk) in monotouch. I have created wrapper for red park dll by using monotouch binding project and implement the dll in simple application. On assigning the delegate the application crashes. This my code for assigning the delegate

rsc=new RscMgr();
            RscMgrDelegate del=new MyRedParkDelegate();

            System.Diagnostics.Debug.WriteLine("this"+del);
            rsc.SetDelegate(del);

The crash i’m getting is

    Save RscMgrDelegate in a member variable in your class.

    If the Garbage Collector is able to collect it (it’s not saved in a variable that stays around), then Objective-C will crash when it tries to invoke it. This could more likely happen on the device, since the Garbage Collector runs more aggressively.
