This is in response to a post on CodePlex in regards to how to retrieve the metadata of a service.  I based this on a WCF Sample create by Vipul Modi.

DynamicProxyFactory

In the WCF Test Harness solution, the DynamicProxyFactory class is used to generate a proxy class based on a metadata enabled service.  The class performs the following:

1. Downloads Metadata - uses the System.Web.Services.Discovery.DiscoveryClientProtocol to retrieve the metadata
2. Imports Metadata - uses the System.ServiceModel.Description.WsdlImporter to extract the bindings, contracts and endpoints
3. Creates Proxy - generates the proxy code
4. Writes Proxy - writes the code into memory
5. Compiles - compiles the proxy code into a temporary assembly

If you are interested in exploring this, I suggest retrieving the source code and investigating the classes located in the Dynamic folder of the Spike.ContractBuilder library.
