Is it possible to configure a WCF service (with net.tcp bindings) in such a way that it can display a help page as it shows in case of http bindings?
Add a mex endpoint to your service
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
Then add httpGetEnabled to the service's metadata
<serviceBehaviors>
<behavior name="MyServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
Then you should be able to browse the mex endpoint's url with http
EDIT: changed binding to mexHttpBinding instead of mexTcpBinding
