DotNet package doesn't work in latest and release 4.15

[zxpatric]

Tested out with the following steps:

(1) Server. Python. Used python 3.4 and installed pyro4 using pip

def main():
daemon = Pyro4.Daemon() # make a Pyro daemon
uri = daemon.register(CenterController)
print("Ready. Object uri =", uri) # print the uri so we can use it in the client later
daemon.requestLoop()

if name == 'main':
main()

(2) Client. C#. The URI string is coming from the the print out of the python based server

public class TestURI
{
    public static void Run()
    {

        string uri = "PYRO:obj_0de46bb35aa84b729b796b9937cfe6fe@localhost:59773";

        PyroURI pyURI = new PyroURI(uri);

        using (PyroProxy p = new PyroProxy(pyURI))
        {
            dynamic result = p.call("getDst");
            System.Console.WriteLine(result.toString());
        }
    }
}

Exception:
unhandled exception: System.InvalidCastException: Unable to cast object of type
'System.Collections.Generic.Dictionary`2[System.Object,System.Object]' to type '
System.Collections.Hashtable'.

Fix:
PyroProxy.cs
//var response_dict = (Hashtable)handshake_response;
var response_dict = (System.Collections.Generic.Dictionary<Object, Object>)handshake_response;
//_processMetadata(response_dict["meta"] as Hashtable);
_processMetadata(response_dict["meta"] as System.Collections.Generic.Dictionary<Object, Object>);

Conclusion
The return result of functions are now returned as Dictionary type and dictionary table is no more directly castable to hash table...

Thanks for reporting this, I failed testing the previous release properly it seems. Will fix soon.
Note that the issue is only in the .NET library, the Java library works fine.
