MetadataExchangeClient using Web Proxy

I am trying to connect to a URI pointing to a WSDL file which describes a WCF service by using the MetadataExchangeClient class.

var mexClient = new MetadataExchangeClient(uri, MetadataExchangeClientMode.HttpGet);
var metaDocs = mexClient.GetMetadata();

The problem is that I cannot access this uri directly and need to go through a HTTP proxy server. The proxy server URL can change at runtime so I cannot simply configure it through the app.config file.

Where can I specify the proxy server information in the MetadataExchangeClient class?

Anyone got an idea? WCF experts?

You can override the GetChannelFactory and provide an implementation that can create a suitable endpoint i.e. a BasicHtppBinding with the proxy details added.

See here for a clue to how programmatically set Binding.

See here for starting point on creating the Channel Factory (see the 3 comments at the end of the post)

This shows how to use MetadataExchangeClient with a Custom Binding:

Here's the .NET Framework Source to MetadataExchangeClient so you can get a better understanding of what it is doing.

You need to specify the proxy in the app.config like this:

<system.net>
  <defaultProxy enabled="true">
   <proxy bypassonlocal="true"
          proxyaddress="http://proxy.domain.org:8888/" />
  </defaultProxy>
</system.net>
