VS2010 When debugging web.config transforms are not being applied. Building a deployment package works

问题

When I debug a web application, the web.config transforms are not applied. I simply find that the configuration in web.config is not applying the transform for the configuration I'm currently using.

Yet if I build a deployment package then I find that the web.config does have the current transforms applied.

Are transforms not applied when debugging? I'm starting to wonder if this is the case, but I have coworkers insisting that it works for them.

回答1:

Web.config transforms are only applied when publishing or deploying.

Jared Harding provided a link where a member of the .NET Team answered this question in the response here: VS2010 Clean Web.configs - not updating

回答2:

You can start a transform by introducing a "AfterBuild" entry in your project file as described here. Downside: you have 2 web.config files...
