Enable MEX in a Web.Config

Question

How do I enable/create a MEX endpoint in the below web config so I can view the service from my browser?

I have tried a few variation from googling but VS always complai

Answer 1

Just add System.ServiceModel.dll under references of your VS Project where your Web.config file is present.

Then add the below code in Web.config(like other service endpoints):

<endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange"/>

Answer 2

In VS, go Tools > WCF Service Configuration Editor. You can open your web.config and tinker with your WCF endpoints and bindings in a nice GUI that (shouldn't) generate XML that VS will complain about.

Answer 3

Add this line to the web.config right under the service endpoint:

<endpoint address="mex" binding="mexHttpBinding" name="MetadataEndpoint"
 contract="IMetadataExchange" />

Thanks josh3736 for the tip on the GUI editor, the only problem I had was I still didn't know how to use the editor to do this, so here is what I did:

1. In VS, open Tools/WCF Service Configuration Editor
2. Open the web.config or app.config file that contains your service definition
3. Navigate to the Services / (your service) / Endpoints folder
4. If the MetadataEndpoint is there, click on it and edit the configuration to your liking, otherwise, right-click the Endpoint folder then click New Service Endpoint and configure like the one in the image below.
