I have web service like the following
[ServiceContract] [ServiceKnownType(typeof(test))] interface ItestbService {     [OperationContract]     IList RetrieveTestList(); }  public class TestWebService : ItestbService {     [WebInvoke(UriTemplate = "RetrieveTestList", Method = "GET", ResponseFormat = WebMessageFormat.Json,RequestFormat = WebMessageFormat.Json)]     public IList RetrieveTestList()     {         return new test().ListOftests();     }

then in separate project I hosted it using the following code using svc file using the following line

<%@ ServiceHost Language="C#" Debug="true" Service="test.WebService.TestWebService" CodeBehind="test.WebService.TestWebService.cs" %>

and this is the web.config

         name="test.WebService.TestWebService">        address="" binding="webHttpBinding" contract="test.WebService.ItestbService" behaviorConfiguration="web">                               name="web">          />          maxItemsInObjectGraph="2147483647"/>                                  maxItemsInObjectGraph="2147483647" />          httpGetEnabled="true" />          includeExceptionDetailInFaults="true" />                               name="defaultRest">          maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="64" maxNameTableCharCount="2147483647" />          mode="None" />                   multipleSiteBindingsEnabled="true" />
