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.

If you go into Tools > Options > Keyboard and search in the "Show commands containing" search box search for "BrowserLink". Find the option that says "OtherContextMenus.BrowserLink.RefreshLinkedBrowsers" by default this is set to CTRL+Alt+Enter. Click "Remove" and then select the "Press Shortcut Keys" input and press Ctrl+S. Next (just to the left of the input) change Use new shortcut in "Global" to be "Text Editor". Click "Ok" until the window has closed. Now Visual Studio shares CTRL+S with both Saving files and Refreshing linked browsers.

(This will only work if your text editor .cshtml, .css, .js, etc. files in the edit window are the active selections) WARNING: if you don't set it to something other than global then it will override the shortcut for Save and you won't be able to save your files.

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();
