WCF endpoints stored in app.config or web.config?

Question

When I create the WCF services library, app.config is created for me, where I put the endpoints. Then, if I create a website and link to the WCF services library, it creates a web.config file where I can specify the endpoints. Do I put endpoints in app.config or web.config or should they be in both?

Essentially, it is Web.config , if you host services in IIS, app.config , if you are a self-hosting. It looks like you want to put them in Web.config .

Details can be found here where MSDN says:

When configuring a service in Visual Studio, use either the Web.config file or the App.config file to specify Settings. Select the name of the configuration file for your chosen hosting environment for maintenance. If you use IIS to host your service, use the Web.config file. If you use any other hosting, use the App.config file.

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