    <p>I want create dynamic WCF service channel in VS-2010 using ChannelFactory as follows.</p> <p>I have one WCF service which is calling another WCF service using ChannelFactory as follows,</p> <pre><code>BasicHttpBinding myBinding = new BasicHttpBinding(); EndpointAddress myEndpoint = new EndpointAddress(_endpointConfigurationName); using (ChannelFactory&lt;IService&gt; factory = new ChannelFactory&lt; IService &gt;(myBinding)) { factory.Open(); object[] parameters = new object[1]; parameters[0] = _documentId; IService proxy = factory.CreateChannel(myEndpoint); if (proxy == null) return; MethodInfo mi = proxy.GetType().GetMethod("DoExecute"); if (mi == null) return; var serviceResult = mi.Invoke(proxy, parameters); factory.Close(); } </code></pre> <p>“Web.config” file of called service as follows,</p> <pre><code>&lt;services&gt; &lt;service name="IService.Service"&gt; &lt;endpoint address="ws" binding="wsHttpBinding" name="wsHttpBinding_IFTPUploaderService" contract="Service.IService "&gt; &lt;identity&gt; &lt;dns value="localhost" /&gt; &lt;/identity&gt; &lt;/endpoint&gt; &lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /&gt; &lt;host&gt; &lt;baseAddresses&gt; &lt;add baseAddress="http://localhost:8752/Service/" /&gt; &lt;/baseAddresses&gt; &lt;/host&gt; &lt;/service&gt; &lt;/services&gt; </code></pre> <p>factory and proxy is working fine but when “Invoke” method is executed it gives error as follows</p> <p>There was no endpoint listening at <code>http://localhost:81/IService.Service.svc?wsdl</code> that could accept the message. This is often caused by an incorrect address or SOAP action.

    1. COWhy are you using reflection here to get the member? Based on the snippet this proves little to no sense to do.

    3. COBased on the config file of the service you're calling, you should be using `WSHttpBinding` (not `BasicHttpBinding`), and as @zimdanen pointed out the address should be something like `http://localhost:8752/Service/ws`.

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.

SQuiL has stopped working due to an internal error.

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