Closed Issue: Attempting to use V15.1.4 with an Empty ASP.Net Web Application [27977]

Attempting to use V15.1.4 of AJAX Control Toolkit with Visual Studio 2015 and an Empty ASP.Net Web Application. The Toolbox shows the Toolkit tab but all of the controls are greyed out and the tab only shows up if I tell it to show me all tabs. The documentation shows using it with a regular ASP.NET Web Application but I do not want all of the overhead of that kind of a project. Any ideas what I need to do to make it work with my Empty Web Application?

Thanks

Mike
