I am attempting to setup Team City for CI on my project. We currently have 9 developers working on the project and using Mercurial for source control. Right now all web.config files are ignored in the main project repo and the web.config files are located in a separate repo so that we do not have to use a dozen transforms.
How can I configure Team City/MS Build so I can checkout both repos (have this working so far) and then update the repos and copy the web.config to the main project folder before doing the build?
