Question

I am using VSTS 2008 + C# + .Net 3.0. I am using self-hosted WCF. When executing the following statement, there is the following binding not found error. I have posted my whole app.config file, any ideas what is wrong?

ServiceHost host = new ServiceHost(typeof(MyWCFService));

Error message,

Configuration binding extension 'system.serviceModel/bindings/MyBinding' could not be found. Verify that this binding extension is properly registered in system.serviceModel/extensions/bindingExtensions and that it is spelled correctly.

Full app.config,

You’ve misunderstood how to configure bindings – your binding in the endpoint needs to be a known protocol;

 <endpoint address="" binding="wsHttpBinding" contract="IMyService"/>

Once you have that you can then specify the binding configuration you have defined within the settings for that protocol using the bindingConfiguration element thus

 <endpoint address="" binding="wsHttpBinding" 
  bindingConfiguration="MyBinding" contract="IMyService"/>
