缺少 startup.cs program.cs .Net Core 剃刀
Missing startup.cs program.cs .Net Core Razor
我有一个使用 Razor 页面的 .Net Core 3 Web 应用程序。几天前我在弄乱解决方案资源管理器,现在我发现我缺少 startup.cs 和 program.cs。我怎样才能恢复它们?我也收到此错误:"Unable to run your project. The RunCommand property is not defined".
首先我会检查以确保您的文件在项目目录中,然后再尝试重建它们。如果它们仍在目录中,您可以使用 Visual Studio.
将它们添加到您的解决方案中
Right click the project > Add > Existing item...
如果您没有这些文件并且找不到它们,请重新创建它们。这是它们的默认代码。
