MVC 4 Project - Bundling and Minification is not working

Question

Dear All,

I have a JQuery Project which is built on MVC4 framework, which is getting Bundling and minification without any issue using AJAX minifier old technology,in that project there is no AppStart folder (BundleConfig.cs) and Global.asax file in this project , still Bundling and minification works fine. So I have copied the same project and trying to modify as per my requirement, But my version of the same Project is not getting bundled or minified.

Could you please let me know, what mistakes I am doing.

Old Project was in Targetframework 4.5 but my Project is in .Net framework 4.7.2 version due to .Net core service. So Except framework version diffrence I have copied all the necessary files which was present on the old Project to my new project, still its not getting bundled/minified.
