Dylan,

If you go to http://localhost/hello?wsdl in your browser, do you get
anything?

If you use a "hello world" svc file hosted in IIS (which you can get
by installing the WCF/WPF CTP onto VS2005), then simply browsing to
the svs tells you exactly how to enable mex. To quote (and note the
link at the bottom):

================

Service


This is a Windows© Communication Foundation service.

Metadata publishing for this service is currently disabled.

If you have access to the service, you can enable metadata publishing
by completing the following steps to modify your web or application
configuration file:

1. Create the following service behavior configuration, or add the
<serviceMetadata> element to an existing service behavior
configuration:

<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors" >
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>

2. Add the behavior configuration to the service:

<service name="MyNamespace.MyServiceType"
behaviorConfiguration="MyServiceTypeBehaviors" >

Note: the service name must match the configuration name for the
service implementation.

3. Add the following endpoint to your service configuration:

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

Note: your service must have an http base address to add this
endpoint.

The following is an example service configuration file with metadata
publishing enabled:

<configuration>
<system.serviceModel>

<services>
<!-- Note: the service name must match the configuration
name for the service implementation. -->
<service name="MyNamespace.MyServiceType"
behaviorConfiguration="MyServiceTypeBehaviors" >
<!-- Add the following endpoint. -->
<!-- Note: your service must have an http base address
to add this endpoint. -->
<endpoint contract="IMetadataExchange"
binding="mexHttpBinding" address="mex" />
</service>
</services>

<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors" >
<!-- Add the following element to your service
behavior configuration. -->
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>

</system.serviceModel>
</configuration>

For more information on publishing metadata please see the following
documentation: http://go.microsoft.com/fwlink/?LinkId=65455.

Hi,

When I put http://localhost/hello?wsdlin in the browser,

I get the Service page and this message at the top: "Metadata
publishing for this service is currently disabled"
I guess I have not hosted my the service properly and have not enabled
metadata publishing.

I guess I have not hosted my the service properly and have not enabled

metadata publishing.

The two aren't related. The fact you see something other thant a
yellow-screen-of-death tells me it is hosted fine. Metadata publishing
isn't enabled by default, but just follow the steps it cites.
