.cshtml 更改时，为什么刷新后页面不更新 [英] Why does page not update after refresh when .cshtml changes

问题描述

我正在尝试 Blazor，但我不明白为什么在刷新浏览器页面后更改 component 时它没有更新?client 不应该像 angular 那样更新自己吗?

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?

它仅在我重新启动 blazor 服务器时刷新.

It only refreshes when i restart the blazor server.

Index.cshtml

@page "/"

<h1>Hello, world!</h1>

如果我将 <h1> 中的文本更改为 Hello people ，我将保存项目并刷新页面(正如我在Blazor 教程)我不应该看到 Hello people 吗?

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 ?

推荐答案

在 Asp.net Core 3.0 之后，使用 Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation 包启用运行时编译.要启用运行时编译，应用必须:

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

安装 Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet 包.

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

更新项目的 Startup.ConfigureServices 方法以包含对 AddRazorRuntimeCompilation 的调用:

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

services
    .AddControllersWithViews()
    .AddRazorRuntimeCompilation();

或

services.AddMvc().AddRazorRuntimeCompilation();
