Chapter 11: Deploying Web Services with WCF 323
When you create a new WCF Service project, VS adds a file named app.config to
the project, which is a file that belongs only to VS. The app.config file is never deployed
with your Web service, but it generates a file named web.config, which is deployed
with the project. In WPF projects, VS uses the app.config file to generate a file named
projectname.exe.config in the same folder as the projectname.exe file. WCF Service
projects don’t generate a config file in the output folder, but they do generate a web.config
file when you deploy. You’ll see web.config soon, after deployment.
During development, you work with the app.config file, which is easy to find and
open in your project. The app.config file has a lot of information in it, so Listing 11-6 is a
small excerpt that shows you the salient elements of the WCF configuration.
