I have the followings:

In Competitions.svc:

XML

<%@ ServiceHost Language="C#" Debug="true" Service="MySite_WebSite.Pages.Client.CompetitionsSVC" CodeBehind="Competitions.svc.cs" %>

In ICompetitions.cs :

C#

namespace MySite_WebSite.Pages.Client
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "ICompetitions" in both code and config file together.
    [ServiceContract(Name="CompetitionsSVC")]
    public interface ICompetitions
    {
        [OperationContract]
        [WebInvoke(
            Method = "GET"
            , RequestFormat = WebMessageFormat.Json
            , ResponseFormat = WebMessageFormat.Json
            , UriTemplate = "DoWork"
            , BodyStyle=WebMessageBodyStyle.Wrapped
        )]
        Dictionary<DateTime, List<Competitions.Entry>> DoWork();
    }
}

In Competitions.svc.cs :

C#

namespace MySite_WebSite.Pages.Client
{
    [DataContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class CompetitionsSVC : ICompetitions
    {
        #region ICompetitions Members

        public Dictionary<DateTime, List<Competitions.Entry>> DoWork()
        {
            var c = new Competitions();

            return c.GetMonthlyEntries(new Competitions.ParamGetMonthlyEntries()
            {
                Start = DateTime.Now.Date.AddMonths(-1)
                , End = DateTime.Now.Date.AddMonths(2)
                , UserLang = "fr-BE"
                , ActiveLang = "fr-BE"
                , IsExternal = false
            });
        }

        #endregion
    }
}

In Web.config:

When I enter the url

localhost2/MySite_WebSite/Pages/Client/Competitions.svc/DoWork

, it doesn't work.
I have a breakpoint at the begining of the method, and I can see the method gets called twice, yet it doesn't return anything (I don't even think it send any HTTP code backs).

What did I do wrong?

This is not a solution but it looks like i can't show code in a comment so this was the way i thought was best to show my question.

are you sure your code:

C#

return c.GetMonthlyEntries(new Competitions.ParamGetMonthlyEntries()
{
   Start = DateTime.Now.Date.AddMonths(-1)
    , End = DateTime.Now.Date.AddMonths(2)
    , UserLang = "fr-BE"
    , ActiveLang = "fr-BE"
    , IsExternal = false
});

returns a value?

if that returns null its normal that you don't see anything.

can you try to do something like:

C#

Dictionary<datetime,>> dictionaryList = c.GetMonthlyEntries(new Competitions.ParamGetMonthlyEntries()
{
   Start = DateTime.Now.Date.AddMonths(-1)
    , End = DateTime.Now.Date.AddMonths(2)
    , UserLang = "fr-BE"
    , ActiveLang = "fr-BE"
    , IsExternal = false
});

return dictionaryList;

put a break point on that return statement.
and when the program stops check if dictionaryList is not null or empty

Ok, I solved the problem.

I use a custom piece of code to serialize the dictionnry into a JSON string and I don't use DateTime objects as keys anymore (as those aren't valid keys for a JSON dictionary).

C#

public Stream Test()
{
    var c = new Competitions();
    var result = c.GetMonthlyEntries(new Competitions.ParamGetMonthlyEntries()
    {
        Start = DateTime.Now.Date.AddMonths(-1)
        , End = DateTime.Now.Date.AddMonths(2)
        , UserLang = "fr-BE"
        , ActiveLang = "fr-BE"
        , IsExternal = false
    }).ToDictionary(
        kp => kp.Key.ToString("yyyy-MM-dd")
        , kp => kp.Value
    );

    var javaScriptSerializer = new JavaScriptSerializer();
    var json = Encoding.UTF8.GetBytes(javaScriptSerializer.Serialize(result));
    var memoryStream = new MemoryStream(json);
    WebOperationContext.Current.OutgoingResponse.ContentType = "application/json; charset=utf-8";
    return memoryStream;
}
