Visual studio editor showing as miscellaneous files

I have recently installed visual studio 2019. after creating the controller it showing editor as miscellaneous files. The project was created on VS2015. I had a problem not able to create view. So I found solution, went to manage nuget and updates the Microsoft.Net.Compilers to 3.x.x
