.Net Core 前端运行时编译无效的解决方法

官方文档：https://docs.microsoft.com/zh-cn/aspnet/core/mvc/views/view-compilation?view=aspnetcore-3.0&tabs=visual-studio

1.首先需要安装运行时编译包；  直接下载地址：  https://www.nuget.org/packages/Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation/；也可以复制命名空间在nuget下自主安装；

Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation

2.修改Properties下单launchSettings.json;在environmentVariables节点下添加  ASPNETCORE_HOSTINGSTARTUPASSEMBLIES，并设置为 "Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" 即可；

"environmentVariables": {
 "ASPNETCORE_ENVIRONMENT": "Development",
 "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation"
}

 

 

 3.在Startup=>ConfigureServices,添加   services.AddRazorPages().AddRazorRuntimeCompilation();重新运行即可
