直接在 razor 頁面裏添加 <PageTitle>xxx</PageTitle> 標籤無效時的解決方法
For using the <PageTitle> tag with the new version of .NET Core, server-side and not webAssembly, you need replace your <title> tag with a new component and add his library into the file Pages/_Host.cshtml.
@using Microsoft.AspNetCore.Components.Web <head> <component type="typeof(HeadOutlet)" render-mode="ServerPrerendered" /> </head>
Project scafolding created from .Net Core 6 add these parts automatically in Pages/_Layout.cshtml
Teorically, users with migrating WebAssembly projects need add too the code on below in Program.cs
builder.RootComponents.Add<HeadOutlet>("head::after");
