WCF Typed Service Moinker Contract

  • Article

When using a typed service moniker, the contract specifies the UUID of the interface for the contact (IInteropTest) defined in the web.config of the WCF service. The UUID can be located by viewing the type library for the registered assembly (i.e. InteropTestProxy.tlb) using Oleview.exe.

Strong Named Proxy Assembly
