  1. POWCF Address Already In Use after adding client endpoint
    text
    copied!<p>I have a WCF Service that is self hosted and started through another service. Debugging in visual studio, they work just fine until I add endpoint configurations to my <code>app.config</code> for the service clients. Some clients for this service will be local and others remote. I have tried only having client endpoints for named pipes, if there's a client endpoint pointing to the service, and a client using the endpoint (even though it shouldn't even be instantiated at the point the service tries to start) I get an exception telling me that 0.0.0.0:8524 is in use. Here's the relevant configuration:</p> <pre><code>&lt;service name="EventService.EventPublishingService"&gt; &lt;clear /&gt; &lt;endpoint binding="netTcpBinding" address="net.tcp://localhost:8524/EventPublishingService" contract="EventService.Contracts.IEventPublishService"&gt; &lt;/endpoint&gt; &lt;endpoint address="net.tcp://localhost:8524/EventPublishingService/mex" binding="mexTcpBinding" contract="IMetadataExchange"&gt; &lt;/endpoint&gt; &lt;endpoint address="net.pipe://localhost/EventPublishingServicePipe" binding="netNamedPipeBinding" contract="EventService.Contracts.IEventPublishService" listenUriMode="Explicit"&gt; &lt;/endpoint&gt; &lt;host&gt; &lt;/host&gt; &lt;/service&gt; </code></pre> <p>For client endpoints I have tried both</p> <pre><code>&lt;endpoint address="net.tcp://localhost:8524/EventPublishingService" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IEventPublishService" contract="AGX.Atlas.EventService.Contracts.IEventPublishService" name="NetTcpBinding_IEventPublishService"&gt; &lt;/endpoint&gt; </code></pre> <p>and</p> <pre><code>&lt;endpoint address="net.pipe://localhost/EventPublishingServicePipe" binding="netNamedPipeBinding" bindingConfiguration="NetNamedPipeBinding_IEventPublishService" contract="AGX.Atlas.EventService.Contracts.IEventPublishService" name="NetNamedPipeBinding_IEventPublishService"&gt; &lt;/endpoint&gt; </code></pre> <p>I've removed the net.pipe binding from the service when removing the client binding as well to make sure it wasn't doing something weird with that. Still the same issue.</p> <p>Here's the binding configurations:</p> <pre><code> &lt;netNamedPipeBinding&gt; &lt;binding name="NetNamedPipeBinding_IEventPublishService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;security mode="Transport"&gt; &lt;transport protectionLevel="EncryptAndSign" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/netNamedPipeBinding&gt; &lt;netTcpBinding&gt; &lt;binding name="NetTcpBinding_IEventPublishService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /&gt; &lt;security mode="Transport"&gt; &lt;transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /&gt; &lt;message clientCredentialType="Windows" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;binding name="NetTcpBinding_IEventSubscriptionService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /&gt; &lt;security mode="Transport"&gt; &lt;transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /&gt; &lt;message clientCredentialType="Windows" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/netTcpBinding&gt; </code></pre>
