WCF Error in Deserializing the Request Message Body to Work

Question

I have an asp.net client web application and a WCF web service that was developed from an xsd schema. When I call the service, I get an error in deserializing the request body. I tried to update the service link, but that did not help.

This is my code:

OSEOP.HMA_OrderingBindingClient client = new OSEOP.HMA_OrderingBindingClient();

OSEOP.GetCapabilitiesRequest request = new OSEOP.GetCapabilitiesRequest();
request.GetCapabilities = new OSEOP.GetCapabilities();
request.GetCapabilities.service = "OS";

string[] arrAcceptedVersions = { "1.0.0", "2.0.0" };
request.GetCapabilities.AcceptVersions = arrAcceptedVersions;

OSEOP.Capabilities capabilities = client.GetCapabilities(request.GetCapabilities);


txtGetCapabilitiesResponse.Text = capabilities.Contents.ToString();

client.Close();

and this is a mistake:

System.ServiceModel.FaultException`1 was unhandled by user code
  Message=Error in deserializing body of request message for operation 'GetCapabilities'.

  InnerException: 

as you can see, the error occurs at the client and is never sent to the WCF service. For this reason, I am not getting anything in my MessageLogging. This is why I thought it would be linked to a service link.

Can anyone help?

EDIT # 1: I do not understand that GetCapabilities accepts the GetCapabilitiesRequest parameter, but when I implement the client, my intellisense requests an OSEOP.GetCapabilities object.

OSEOP is what I called a web link.
