I have reinstalled my VS 2019 and cloned my applications on my machine. But suddenly all the applications stopped showing add -> Controller --> MVC 5 Controller and its View. After rebuild my application is converted into Razor from MVC Core 3.1. and now all applications throws error of g.cshtml.cs file. Help me to fix this issues.

1. 为什么将.net核心MVC应用程序转换为Razor.
2. 为什么应用程序未添加MVC控制器和视图.

推荐答案

1. 创建一个空的ASP.NET Core MVC项目

将 Endpoint 路由更改为 MVC 路由.

    public void ConfigureServices(IServiceCollection services)
    {
        //services.AddControllersWithViews();

        #region 2.2 MVCRouterConfigure
        services.AddMvc(options =>
        {
            options.EnableEndpointRouting = false;
        }).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
        #endregion
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        //app.UseRouting();

        app.UseAuthorization();

        app.UseMvc();

        //app.UseEndpoints(endpoints =>
        //{
        //    endpoints.MapControllerRoute(
        //        name: "default",
        //        pattern: "{controller=Home}/{action=Index}/{id?}");
        //});
    }

1. 设置剃须刀页面

现在您已经创建了项目，让我们准备好使用 Razor Pages .

Now that you have created the project, let's prepare it to use Razor Pages.

首先在项目的根文件夹下创建一个名为 Pages 的文件夹.默认情况下，剃须刀页面存储在Pages文件夹中，并且可以以Pages为根从浏览器进行访问.例如，如果您在文件夹中放置了 Index.cshtml ，则可以将其作为 https://localhost:44366/Index

Begin by creating a folder named Pages under project's root folder. By default razor pages are stored inside Pages folder and can be accessed from the browser with Pages as their root. For example, if you have Index.cshtml housed inside Pages folder then it can be accessed as https://localhost:44366/Index

添加剃须刀页面.右键单击Pages文件夹，然后选择 Add >新商品.选择剃刀页面"项，并将名称指定为 Index.cshtml .点击添加按钮.您将观察到两个文件- Pages 文件夹中的 Index.cshtml 和 Index.cshtml.cs .

To add a razor page. right click on the Pages folder and then select Add > New Item. Select Razor Page item and specify name as Index.cshtml. Click on the Add button. You will observe that two files - Index.cshtml and Index.cshtml.cs in Pages folder.

您可以在Pages文件夹下创建其他文件夹树.根据页面的位置，其URL将更改.例如，如果将 Hello.cshtml 存储在/Pages/Test 下，则可以在http://localhost:12345/Test/Hello

You can create further folder tree under Pages folder. According to the page's location its URL will change. For example, if you store Hello.cshtml under /Pages/Test then you can access it at http://localhost:12345/Test/Hello
