Also one more thing, the web.config transform doesn't overwrite or generate a new web.config under your project folder, rather a new one is created under "obj\<config name>\..." for deploy. We don't touch the original web.config because that has settings specfically
for your local development machine, while transformation is used to transform some artifacts to hosting server environment such as new data connections pointing to live data server.
Hope it helps,
