Question

When I create a WCF Service Library, an app.config is generated for me where I put the end points. Then if I create a website and reference the WCF Service Library, it creates a web.config file where I can specify the end points. Do I put the end points in the app.config or web.config or do they have to be in both?

Essentially, it’s Web.config if you’re hosting the services in IIS, app.config if you’re self hosting. So it sounds like you want to put them in the web.config.

Full details can be found here where MSDN says:

When configuring a service in Visual
Studio, use either a Web.config file
or an App.config file to specify the
settings. The choice of the
configuration file name is determined
by the hosting environment you choose
for the service. If you are using IIS
to host your service, use a Web.config
file. If you are using any other
hosting environment, use an App.config
file.

In Visual Studio, the file named
App.config is used to create the final
configuration file. The final name
actually used for the configuration
depends on the assembly name. For
example, an assembly named
“Cohowinery.exe” has a final
configuration file name of
“Cohowinery.exe.config”. However, you
only need to modify the App.config
file. Changes made to that file are
automatically made to the final
application configuration file at
compile time.
