Why infrastructure folder does not add automatically in my solution on MVC 5

I am learning MVC from ASP.NET MVC 5 Live Lessons.

My problem is when instructor create new project he has some additional folders there in his solution but in my solution those folders are not exist, such as Infrastructure.

I don't know what is the reason behind that. The reason why I am asking this question is that the instructor uses some class from infrastructure folder that classes are not exist in my project so that I cant use them.

Can anyone please help me to get rid of this problem?
