Why does page not update after refresh when .cshtml changes

I am trying out Blazor and i do not understand why when changing a component after refreshing the browser page it does not update ? Shouldn't the client update itself similar to how angular does?

It only refreshes when i restart the blazor server.

Index.cshtml

@page "/"

<h1>Hello, world!</h1>

If i change lets say the text inside the <h1> to Hello people , i save the project and i refresh the page ( as i am advised in the Blazor tutorial) shouldn't i see Hello people ?

After Asp.net Core 3.0, Runtime compilation is enabled using the Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation package. To enable runtime compilation, apps must:

Install the Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package.

Update the project's Startup.ConfigureServices method to include a call to AddRazorRuntimeCompilation:

services
    .AddControllersWithViews()
    .AddRazorRuntimeCompilation();

or

services.AddMvc().AddRazorRuntimeCompilation();  

I guess you are running the app with the debugger connected? this prevents the recompilation. You need to:

Press Ctrl-F5 to run the app without the debugger. Running with the debugger (F5) isn't supported at this time.

You should add or enable runtime compilation in razor pages,

Install-Package Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation -Version 3.1.6

After installing set the startup file as ,

 services.AddMvc().AddRazorRuntimeCompilation();

do the following:

1. Install the Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation from NuGet.

2. Update the ConfigureServices method in the Startup class to look like below:

services.AddControllersWithViews().AddRazorRuntimeCompilation();

3. You good to go.
