I've created a fulltrust proxy:

string assembly = "FullTrustProxyExecise1, Version=, Culture=neutral, PublicKeyToken=21621f0ea660fe24";
string type = "FullTrustProxyExecise1.WSCreatorProxy";
WSCreatorProxyArgs args = new WSCreatorProxyArgs();
args.Filename = filename;
args.Siteurl = siteurl;
string url=(string) SPUtility.ExecuteRegisteredProxyOperation(assembly, type, args);
return url;

This however gives an Exception:

"Operation is not valid due to the current state of the object."

I've checked with PowerShell if the proxy is available, it is.

Hints anyone ?
