If I create a Cache object from HttpRuntime.Cache then try to create and start
an HttpListener the program crashes with an unhanded exception.

I can successfully instantiate these objects independently, but together things
blow up.  Thank you.

Reproducible: Always

Steps to Reproduce:
// instantiating a Cache object before a HttpListener object
// crashes the Start() method.    

    Cache cache = HttpRuntime.Cache;
    cache["hello"] = "world";

    System.Net.HttpListener listener = new System.Net.HttpListener();
    listener.Prefixes.Add("http://192.168.1.101:8081/");
    listener.Start();

     Console.WriteLine(listener.IsListening); 
Actual Results:  
Unhandled Exception: System.TypeInitializationException: An exception was
thrown by the type initializer for System.Net.Sockets.Socket --->
System.NullReferenceException: Object reference not set to an instance of an
object

Expected Results:  
HttpListener object should listen on prefix, not causing an unhandled
exception.
