    <p>I am new to WCF and was testing a simple example, with which I got stuck for too long. The error or things I missed might be stupid, but please help me with it. Thanks a lot in advance.</p> <p>Here comes my description of the problem:</p> <p>I was testing a WCF service with json enabled, which is implemented in my <code>CalService.svc.cs</code> file by the following code:</p> <pre><code>namespace SharePoint.WebServices { [ServiceContract] public interface ICalculators { [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json )] float Weight(float width, float diameter, float size, float factor); } public class Calculators : ICalculators { public float Weight(float width, float diameter, float size, float factor) { return 10f; } } } </code></pre> <p>and my <code>CalService.svc</code> file is like this: </p> <pre><code>&lt;%@ ServiceHost Language="C#" Debug="true" Service="SharePoint.WebServices.Calculators" Factory="System.ServiceModel.Activation.WebServiceHostFactory" CodeBehind="CalService.svc.cs" %&gt; </code></pre> <p>I test it my sample service with IE. I was notified of the <code>no endpoint found</code> message. Thus, I think the problem comes from my web.config file. Here it is:</p> <pre><code>&lt;system.serviceModel&gt; &lt;services&gt; &lt;service name="SharePoint.WebServices.Calculators"&gt; &lt;endpoint address="" behaviorConfiguration="JsonBehavior" binding="webHttpBinding" contract="SharePoint.WebServices.ICalculators" /&gt; &lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /&gt; &lt;/service&gt; &lt;/services&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior&gt; &lt;serviceMetadata httpGetEnabled="true"/&gt; &lt;serviceDebug includeExceptionDetailInFaults="false"/&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name="JsonBehavior"&gt; &lt;webHttp /&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;/behaviors&gt; &lt;serviceHostingEnvironment multipleSiteBindingsEnabled="true" /&gt; &lt;/system.serviceModel&gt; </code></pre> <p>I've checked all the points that are made by folks who replied similar threads regarding json-enabled wcf, but still had the endpoint issue. Please help!</p>

    1. COWell, by default, the browser (like IE) can only execute `GET` commands - but your method expects a HTTP `POST`. You'll need to use a tool like Fiddler or something like that to send `POST` to your service - or add a second method that runs on a `GET` to your service so you can test it in the browser

    2. COAnd make sure the HTTP address you are hitting is correct. I would expect the URL for your POST method is something like this : http://localhost:port/CalService.svc/Weight with request body having something like this width=1&diameter=1&size=1&factor=1

    3. COI guess your are right. I definitely should try handcraft a HTTP Post request to the wcf service. But can you give me a sample of what the HTTP request would be raw format, expecially the body message that contains the parameter? Do you think the parameters are encoded as a JSON string in the HTTP body? I did some search on this, found nothing useful. I am trying to use Fiddler 4 as you suggested.Thanks a lot. @marc_s

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
