Tool to upgrade ASP.NET Web.config from 3.5 to 4.0

Question

I am in the middle of updating some applications from ASP.NET 3.5 to 4.0. The Visual Studio 2010 wizard does an excellent job of converting the project file and the web.config file, but I have several other web.config files for different environments (production, production, etc.), which I also need to update.

Is there a Visual Studio tool, command line utility, or other method for updating these web.config files? I basically need to manually start the same wizard as Visual Studio.

Answer 1

Unfortunately, I never found a way to do this and manually updated the configuration files. As soon as I found out what the wizard did, it was not so difficult to reproduce, but it is a little tiring. Here's a good link to what needs to be changed: msdn.microsoft.com/en-us/library/dd483478.aspx (see the section on updating manually).
