Hi, I am currently writing a web application that's used by the company i work for. As I am not the one installing the appilcation on the server, I want to create a deployment project for it. The app deploys on the server OK, but I want to customize it so I can get the person installing the software to set the SQL Connection string, as well as the URL for the Reporting Services web service. I've tried a few things, but I think I need a way to edit the Web.config in an installer class. I've used the AppSettingsReader to get setings, is there a similar class that writes to the .config files? Is there another possible way to set things like a connection string at install time?
