Calling WCF using Proxy

Question

I am consuming a WCF service whose wsdl is not published on the website. The developers of the service have since given me wsdl file to generate the proxy class from it.

I have successfully successfully generated the file using VS2010 svcutil.exe command. I included the file in the project I am working on, however, when calling for the webservice, there is no request going to the webservice host from the proxy class as evidenced by a third party packet sniffer that I used to check outgoing request and responses.

I am just sending through static information

I am new to WCF service so please advise if there is a part I need to add.

All I see in your proxy is a DataContract. I don't see any methods for you to call against the service. Is this the only code generated by scvutil? — Tim
I also have MusicServiceContract Interface and SubmitRequest class as editted in the code above — user2211448
You're not actually calling a method - you're just newing up a response. You need to make a client and call the service with your request to get the response. — zimdanen

You are currently just newing up a response. You need to create a service client and use that to call the service to get your response.

I'm a C# developer, but I imagine something like this:

Dim client as New MusicServiceContractsClient
Dim songresponse = client.SubmitMusic(request)
