Could not find default endpoint element that references contract

Question

I know this has been beaten to death, but I cannot get this to work as it should. I have a WCF service with several contracts. They all work fine when calling them directly

Answer 1

When it comes down to WCF, it typically requires the configuration to be defined within the config file of the executable that calls it.

Thus, if you are unfortunate enough to having to call a WCF DLL from within a VB6 program (as may be the case when using a COM-interop .NET module, for example), and you need to debug the VB6 program, then you will need to create a VB6.exe.config file in the directory where VB6.exe is located.

Failing to do the above may cause a "Could not find default endpoint element that references contract".

As a workaround, one can load the dll's config file at runtime and then call the constructor of the used Service with a Binding and an EndpointAddress as parameters (obtained from the dll's config).
