Unable to load WCF Webservice

I am trying to load the WCF Webservice http://localhost:8732/LoadTestDemoService.svc?wsdl document in Test complete 7.52.678.7. Every time I attempt to do it, I get the following error:

    "An error occurred while loading types for the web service method GetData."



The same service works fine in my Silverlight application. Here is my service code.

namespace SLApp.Web

{

[ServiceContract(Namespace = "")]

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

public class LoadTestDemoService

{

// Add more operations here and mark them with [OperationContract]

[OperationContract]

[WebGet]

public string GetData(int value)

{

return string.Format("You entered: {0}", value);

}

[OperationContract]

[WebGet]

public List<CaseItem> GetCases()

{

List<CaseItem> caseitems = new List<CaseItem>();

caseitems.Add(new CaseItem() { CaseId = 1, CaseName = "Case Name 1" });

caseitems.Add(new CaseItem() { CaseId = 2, CaseName = "Case Name 2" });

caseitems.Add(new CaseItem() { CaseId = 3, CaseName = "Case Name 3" });

caseitems.Add(new CaseItem() { CaseId = 4, CaseName = "Case Name 4" });

caseitems.Add(new CaseItem() { CaseId = 5, CaseName = "Case Name 5" });

return caseitems;

}

}

public class CaseItem

{

public int CaseId { get; set; }

public string CaseName { get; set; }

}

}



Help will be appriciated.





Thanks!
