While creating a ASP.NET MVC Core Web app using VS2017 / 2019, came across that \'Add Areas\' option is missing from Context menu.
Area is not removed from VS 2017/19 but it is moved in Scaffolding and you can access the area using below steps:
1) Right click on your project and click on Add>New Scaffolded Item
2) After click choose the MVC area from the Menu:
3) After choosing give it Name, and after this the Area will be added to your project:
Hope it will helps.
