extenderControlBase file missing from web application

I have recently upgraded from a website project to a web application project in visual studio.
I am using VS 2013.

Since then my confirm button extenders are not working as the project is requesting the ExtenderControlBase file and cannot find it.

I have reinstalled the AjaxToolKit using nuget(I am using the latest version), and it did not solve the problem.

I have also checked that the AjaxMin.dll is in the references folder/bin folder of my project.

I have also added in the Property of the solution, (debug source file tab) the file that the app is looking for (f:\TeamCity\buildAgent\work\80acd78aa4c25314\Server\AjaxControlToolkit\ExtenderBase\ExtenderControlBase.cs), but it did not make any difference.

I don't know what else to do.

Thank you for help in advance

I have recreated the web application already.

However I think I found the solution. I recreated again the web application and this time I did not install the ajaxcontrol toolkit.
When I needed the extender I pulled it from the toolbox.
It is working so far.

Now what is interesting is that the Ajax.min is not referenced in the project.

1) How are you using the extenders?  

2) If you create another temporary web project, and try to use the extenders, do you have the same problem?

I am not sure what ajax.min is for?  AJAX minifier?
