My team uses Team City to do continuous builds and deployment of our Web Application Projects. In order to do a deployment build, we use Web Deployment Projects, which are not available in Visual Studio 2012. We aren't really using any of the advanced features of WDPs like .config transformations, but the main reason we use them is because when they build, they put only the necessary files for deployment into the build folder - in essence, removing all the .cs files and leaving only what's needed for "xcopy deployment". We then rsync the result to our test/prod environments.
So, my question is this: now that WDPs are no longer supported in Visual Studio 2012, how do I do an automated deployment build that pares down to only the files needed for deployment in VS2012?
