Until now I used dreamweaver and asp and now I'm starting in Asp.Net with visual studio 2017. The design view is very bad, it does not look like anything to the actual view of the page in the browser. In Dreamweaver it usually seems quite, although sometimes not.

How can I work in Visual Studio if the view does not look like? How can you improve visualization?
