c# - Different application settings depending on configuration mode

Question

Is anyone aware of a way that I can set application (or user) level settings in a .Net application that are conditional on the applications current development mode? IE: Debug/Release

To be more specific, I have a url reference to my webservices held in my application settings. During release mode I would like those settings to point to http://myWebservice.MyURL.com during debug mode I would love those settings to be http://myDebuggableWebService.MyURL.com.

Any ideas?

This is somewhat late to the party, but I stumbled upon a nice way of implementing the web.transform approach for app.config files. (i.e. it makes use of the namespace http://schemas.microsoft.com/XML-Document-Transform)

I think it is "nice" because it is a pure xml approach and doesn't require 3rd party software.

• A parent / default App.config file is descended from, according to your various build configurations.
• These descendants then only override what they need to.

In my opinion this is much more sophisticated and robust than having to maintain x number of config files which get copied in their entirety, such as in other answers.
