    <p>I have a VS2010 MVC3 solution calling 2 WCF services. Everything works fine on my first computer. I have another computer where I installed the same OS, same VS, same SQL Server Express, Same IIS, ... I copied source code of my solution on this second computer. Everything works fine when running the solution.</p> <p>BUT on this second computer:</p> <ul> <li><p>I cannot browse to the service URL !? (1)</p></li> <li><p>I cannot do a "Update service reference" !? (2)</p></li> </ul> <p>(1) When I browse to <strong>http://localhost/PLATONServices/RequestService.svc</strong> I got a HTTP400 BAD REQUEST error.</p> <p>(2) I got a THE REQUEST FAILED WITH HTTP STATUS 400: BAD REQUEST METADATE CONTAINS REFERENCE THAT CANNOT BE RESOLVED: 'http://localhost/PLATONServices/RequestService.svc'.</p> <p>Any idea?</p> <p>Because code source is the same on both computers and everything is OK on the first computer, the problem is somewhere else. I use IIS6 on both computers but I cannot see any differences.</p> <p>I searched all day long without success. </p> <p>Thanks.</p> <hr> <p>UPDATE</p> <p>Here is the trace of WCF:</p> <pre><code>&lt;E2ETraceEvent xmlns="http://schemas.microsoft.com/2004/06/E2ETraceEvent"&gt; &lt;System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system"&gt; &lt;EventID&gt;131075&lt;/EventID&gt; &lt;Type&gt;3&lt;/Type&gt; &lt;SubType Name="Error"&gt;0&lt;/SubType&gt; &lt;Level&gt;2&lt;/Level&gt; &lt;TimeCreated SystemTime="2012-05-13T08:33:37.1384484Z" /&gt; &lt;Source Name="System.ServiceModel" /&gt; &lt;Correlation ActivityID="{5d80ddb2-6cf8-4e65-bc9b-3f4b7b880605}" /&gt; &lt;Execution ProcessName="w3wp" ProcessID="5280" ThreadID="13" /&gt; &lt;Channel /&gt; &lt;Computer&gt;THINKPAD&lt;/Computer&gt; &lt;/System&gt; &lt;ApplicationData&gt; &lt;TraceData&gt; &lt;DataItem&gt; &lt;TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Error"&gt; &lt;TraceIdentifier&gt;http://msdn.microsoft.com/fr-BE/library/System.ServiceModel.Diagnostics.ThrowingException.aspx&lt;/TraceIdentifier&gt; &lt;Description&gt;Throwing an exception.&lt;/Description&gt; &lt;AppDomain&gt;/LM/W3SVC/1/ROOT/PLATONServices-2-129813716146273047&lt;/AppDomain&gt; &lt;Exception&gt; &lt;ExceptionType&gt;System.ServiceModel.ProtocolException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089&lt;/ExceptionType&gt; &lt;Message&gt;There is a problem with the XML that was received from the network.

    1. COAre the WCF related components installed on the second machine? These are configured from the "Turn Windows features on or off" dialog, which can be found in "Add/Remove Programs" in Windows. They are under the "Microsoft .Net Framework 3.5.1" section generally.

    2. COI installed exactly the same as my other computer. I also try to install "WCF HTTP Activation" under "Microsoft .Net Framework 3.5.1" in "Turn Windows Features on or off" but without correcting the problem. Thanks anyway.

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).
