How do I add a tracing interceptor for all classes within Prism?

I am trying to add a tracing interceptor to all the components of my Prism application using an interface interceptor. I almost have this working however the interceptor is having problems with interfaces that declare an event. Has anyone successfully implemented aop tracing for all components without the need for attributes?

Here is my code:

private void AddTracingInterceptor(Type from, IUnityContainer container)
    {
        container.AddNewExtension<Interception>();
        if (from.ToString().StartsWith("StockTraderRI")
            && !from.ToString().EndsWith("View")
            && from.IsInterface)
        {
            try
            {
                container.Configure<Interception>().SetInterceptorFor(from, new InterfaceInterceptor())
                    .AddPolicy("SomePolicy")
                    .AddMatchingRule(new AllMembersMatchingRule())
                    .AddCallHandler(new TraceCallHandler());
            }
            catch (Exception ex)
            {
                Debug.WriteLine("$$$" + from.ToString() + " " + ex.Message);
            }
        }
        else
        {
            Debug.WriteLine("---" + from.ToString());
        }
    }

and this is the exception:
