Add full error messages to the .NET SDK

 try

                PackageId packageId = eslClient.CreatePackage(documentPackage);
            }
            catch (EslServerException serverException) {
            Console.Out.WriteLine( "The server could not complete the request." );

I know it couldn't create the package because that's where my caller got the error.  I'm far more interested in WHY it couldn't create the package (other than "something was null").

Please provide a way to get the actual errors, codes, etc., in the SDK (Version 11.0.1.0 of the Silanis.ESL.dll).
