ASP.NET Core 3.0 applications don’t build views automatically by default when changes are made. Views are built when application compiles and this is expected final state for views. It’s still possible to make ASP.NET Core application build views when changes are made. The most popular case is when application is running in Visual Studio and we are working on cosmetics of view.

Being able to restart an ASP.NET Core web application programmatically can be very useful, especially if you’ve published it on a Linux host – which is what I almost always do, for a bunch of good reasons: if you want to know why, I strongly suggest to read my How to Publish and Deploy an ASP.NET Core Web Application on Linux Centos dedicated guide.
