Invalid tag in web.config file HTTP Error 500.19

Built a c# web app in Visual Studio, installed it on the IIS server. When I try to browse to it locally, I get HTTP Error 500.19 - Internal Server Error - Error Code 0x8007000d, And I can't double click on any of the settings for that app in IIS, it complains about an error in the web.config.

If I remove the line below, I can double click the settings in IIS, but the page doesn't work, so I'm guessing I am missing a prerequisite or something related to this web.config tag, but I can't find it?
