Looking for a solution to "The type 'XXX', provided as the Service attribute value in the ServiceHost directive could not be found." ?

How can I use WCF and DataContracts against Interfaces, rather than classes?

How can I send large messages (eg: large byte[] arrays) over the wire?

How can I host in IIS a *.svc page that doesn't use CodeBehind, but instead uses a class defined in a referenced assembly?

How do I enable server side Tracing to figure out what's going wrong with WCF calls?

What are some Versioning Best Practices?

Is there a way to check whether a Client Endpoint has been configured in the config file?

What will [ServiceContract(Name="...")] affect?

What does [DataMember(Order=1)] actually do? 

For DataMembers/DataContracts, how can I with against interfaces rather than concrete instances?

Error Msg: The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service XAct.Study.WindowsService.WCFServiceImplementation. 
Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract.

Error Msg: Could not find a base address that matches scheme net.tcp for the endpoint with binding MetadataExchangeTcpBinding. Registered base address schemes are [].

Error Msg: This collection already contains an address with scheme net.tcp.  There can be at most one address per scheme in this collection.
