    <p>I have a WCF Service that will only expose HTTP Endpoints, my App.config is this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;configuration&gt; &lt;system.diagnostics&gt; &lt;sources&gt; &lt;source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true"&gt; &lt;listeners&gt; &lt;add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "C:\Users\Developer\Documents\ProjectName\Servicelog.svclog" /&gt; &lt;/listeners&gt; &lt;/source&gt; &lt;/sources&gt; &lt;/system.diagnostics&gt; &lt;appSettings&gt; &lt;add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /&gt; &lt;add key="ClientSettingsProvider.ServiceUri" value="" /&gt; &lt;/appSettings&gt; &lt;system.web&gt; &lt;compilation debug="true" /&gt; &lt;/system.web&gt; &lt;system.serviceModel&gt; &lt;serviceHostingEnvironment aspNetCompatibilityEnabled="false" /&gt; &lt;services&gt; &lt;service name="Project.ServiceOne"&gt; &lt;endpoint address="http://localhost/Project/ServiceOne" binding="webHttpBinding" contract="Project.IServiceOne"/&gt; &lt;/service&gt; &lt;service name="Project.ServiceTwo"&gt; &lt;endpoint address="http://localhost/Project/ServiceTwo" binding="webHttpBinding" contract="Project.IServiceTwo"/&gt; &lt;/service&gt; &lt;/services&gt; &lt;/system.serviceModel&gt; &lt;system.webServer&gt; &lt;httpProtocol&gt; &lt;customHeaders&gt; &lt;add name="Access-Control-Allow-Origin" value="*" /&gt; &lt;add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept"/&gt; &lt;/customHeaders&gt; &lt;/httpProtocol&gt; &lt;/system.webServer&gt; &lt;startup&gt; &lt;supportedRuntime version="v2.0.50727" /&gt; &lt;/startup&gt; &lt;/configuration&gt; </code></pre> <p>I'm running IIS 7.5 (Windows 7 x64 - The full blown Programs and Features one, not Express) to the Default Web Site, the Project application. </p> <p>I can browse to the .svc file and it will tell me the MEX endpoint is not enabled which is fine: It's the behavior i want over that aspect; The problem comes when i try to POST to <code>http://localhost/Project/ServiceOne/ServiceMethod</code>. The method exists in the Service contract and implementation and is also decorated in the interface as a WebInvoke but POST'ing to it will only return HTTP 404's. Decorating a test method with GET and browsing to it results in a 404 served by MapRequestHandler.</p> <p>What is wrong with my App.config file? How can i make those endpoints work?</p> <p>As requested, the Interface:</p> <pre><code>[ServiceContract] public interface IServiceOne { [OperationContract] [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyMethod")] List&lt;String&gt; MyMethod(); } </code></pre>

    3. COI am not familiar with the GET method of communication with WCF because you often need to tweak the UriTemplate to get it to work, it is actually easier to get it to work with the POST method. If you change the method to POST and take out the UriTemplate and it still doesn't work then it is indeed web.config that's the issue.

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.
