I got this error when creating ASP.net core MVC 8 application:

InvalidOperationException: The view 'Edit' was not found. The following locations were searched: 
/Views/Category/Edit.cshtml /Views/Shared/Edit.cshtml

To solve this, I added: builder.Services.AddControllersWithViews().AddRazorRuntimeCompilation();

I never use this service when creating scaffolding.

1. Controllers/CategoryController.cs:
   // GET: Category/Edit/5

       public IActionResult Edit(int? id)
       {
           if (id == null)
           {
               return NotFound();
           }
   
           Category? category = _db.Categories.Find(id);
   
           if (category == null)
           {
               return NotFound();
           }
   
           return View(category); 
       }
   

2. Views/Category/Edit.cshtml:

@model Category
@{
ViewData["Title"] = "Edit";
} 
<h1>Edit</h1>

Can any experts help explain? Is there a way to avoid using the service mentioned above?

Thanks.
