.cshtml更改后，为什么刷新后页面没有更新 [英] Why does page not update after refresh when .cshtml changes

问题描述

我正在尝试Blazor，但我不明白为什么刷新浏览器页面后更改component时它不会更新? client是否应该像angular那样更新自身?

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>内的文本更改为Hello people，则保存项目并刷新页面(如在Blazor教程中建议的那样)，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程序包启用运行时编译. 要启用运行时编译，应用程序必须:

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软件包.

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

更新项目的Startup .ConfigureServices方法包括对AddRazorRuntimeCompilation的调用:

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

services
    .AddControllersWithViews()
    .AddRazorRuntimeCompilation();

或

services.AddMvc().AddRazorRuntimeCompilation();
