我正在尝试添加IServiceCollection.AddOrchardCms();，但出现以下错误：

Error   CS1061  'IServiceCollection' does not contain a definition for 'AddOrchardCms' and no accessible extension method 'AddOrchardCms' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)  WebApplication1 D:\vibhan_pro\CMS\WebApplication1\WebApplication1\Startup.cs    15  Active
