Is it possible in Visual Studio to change the contents of files while the project is running? Or how to speed up the update of the ASP NET project?

Question

ASP.NET

When compiling and running an ASP NET MVC Core project, part of the .cs files is blocked by the studio and in order to change the code, you need to "turn off the assembly", change the code, recompile and run the changed project, wasting time.
Is it possible to build the project on the fly after changing the .cs file and immediately see the updated data in the browser without restarting the entire IIS?
