    copied!<blockquote> <p>The contract name 'IMyService' could not be found in the list of contracts implemented by the service 'MyService'.. ---> System.InvalidOperationException: The contract name 'IMyService' could not be found in the list of contracts implemented by the service 'MyService'.</p> </blockquote> <p>This is driving me crazy. I have a WCF web service that works on my dev machine, but when I copy it to a Virtual Machine that I am using for testing, I get the error that seems to indicate that I am not implementing the interface, but it does not make sense because the service does work on my windows xp IIS. the Virtual machine uses Windows Server 2003 IIS. Any ideas?</p> <p>One thing to note here is that I get this error on my VM even while just trying to access the service in a web browser as the client.</p> <p>Note: I am using principalPermissionMode="UseWindowsGroups", but that is not a problem on my local machine. I just add myself to the appropriate windows group. But no luck on my VM.</p> <p>Config:</p> <pre><code>&lt;configuration&gt; &lt;system.serviceModel&gt; &lt;diagnostics&gt; &lt;messageLogging logEntireMessage="false" maxSizeOfMessageToLog="2147483647" /&gt; &lt;/diagnostics&gt; &lt;services&gt; &lt;service behaviorConfiguration="MyServiceBehaviors" name="MyService"&gt; &lt;endpoint binding="basicHttpBinding" bindingConfiguration="basicHttpBinding" name="MyService" bindingName="basicHttpBinding" bindingNamespace="http://my.test.com" contract="IMyService"&gt; &lt;/endpoint&gt; &lt;/service&gt; &lt;/services&gt; &lt;bindings&gt; &lt;basicHttpBinding&gt; &lt;binding name="basicHttpBinding" maxReceivedMessageSize="2147483647"&gt; &lt;readerQuotas maxStringContentLength="2147483647" /&gt; &lt;security mode="TransportCredentialOnly"&gt; &lt;transport clientCredentialType="Windows" proxyCredentialType="None" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/basicHttpBinding&gt; &lt;netTcpBinding&gt; &lt;binding name="WindowsClientOverTcp" maxReceivedMessageSize="2147483647"&gt; &lt;readerQuotas maxStringContentLength="2147483647" /&gt; &lt;/binding&gt; &lt;/netTcpBinding&gt; &lt;wsHttpBinding&gt; &lt;binding name="wsHttpBinding" maxReceivedMessageSize="2147483647"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;/binding&gt; &lt;/wsHttpBinding&gt; &lt;/bindings&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name="MyServiceBehaviors"&gt; &lt;serviceMetadata httpGetEnabled="true" /&gt; &lt;serviceAuthorization principalPermissionMode="UseWindowsGroups" impersonateCallerForAllOperations="false" /&gt; &lt;serviceCredentials /&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;/behaviors&gt; &lt;/system.serviceModel&gt; &lt;/configuration&gt; </code></pre>
