Set up the Watch Tool in ASP.NET

How Important is Using Dotnet Watch Tool in Asp.net?

One of the exciting features of Asp.Net 5 is to track all changes in code without any need to recompile the entire project. It makes the development process much faster and simpler. If the .Net application is run with IIS express (using Ctlr+F5), then it is possible to make code changes in Visual Studio, save them and see the updated changes by refreshing the browser. However, most of the programmers use only Kestrel for directly launching their apps.
