开发mvc过程中razor页面需要重启才能编译，非常麻烦，能否实现动态编译，微软官方提供了一个包能实现

新建.net 6 mvc项目

安装Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation

修改csproj

<Project Sdk="Microsoft.NET.Sdk.Web">
    <PropertyGroup>
	    <!--下面两行代码是生产环境使用需要添加，测试环境无需处理csproj-->
        <MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
        <RazorCompileOnBuild>false</RazorCompileOnBuild>
    </PropertyGroup>
</Project>

修改program.cs

namespace WebApplication2;

public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);
        var mvcBuilder = builder.Services.AddControllersWithViews();
        //核心代码在这
        if (builder.Environment.IsDevelopment())
        {
            //添加razor页面动态编译
            mvcBuilder.AddRazorRuntimeCompilation();
        }
        var app = builder.Build();
        app.UseRouting();
        app.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
        app.Run();
    }
}

目前测试.net8不行
