how much of the app.config of a WCF Service Library has to be copied over to app.config of a Console Host?

Question

WCF服务库中有多少app.config必须在控制台主机的app.config中重复？

Answer 1

Basically: everything.

The app.config for the WCF service class library will not be read by .NET.

You need to have all the settings (more specifically: everything in <system.serviceModel> section) into your host application's app.config file.

@Broyian: WCF configuration is a notoriously difficult and often not very well understood topic. I have two video show episodes that I really like that helped me understand configuration a lot better - check them out!

Answer 2

I may not understand the question, but if you are trying to get rid of the app.config in a WCF client application (ie to put everything inside of a DLL), see here
