Automatically generate lowercase dashed routes in ASP.NET Core

Question

ASP.NET Core uses CamelCase-Routes like http://localhost:5000/DashboardSettings/Index by default. But I want to use lowercase routes, which are delimitted by dashes: http://

A little late to the party here but.. Can do this by implementing IControllerModelConvention.

 public class DashedRoutingConvention : IControllerModelConvention
 {
        public void Apply(ControllerModel controller)
        {
            var hasRouteAttributes = controller.Selectors.Any(selector =>
                                               selector.AttributeRouteModel != null);
            if (hasRouteAttributes)
            {
                // This controller manually defined some routes, so treat this 
                // as an override and not apply the convention here.
                return;
            }

            foreach (var controllerAction in controller.Actions)
            {
                foreach (var selector in controllerAction.Selectors.Where(x => x.AttributeRouteModel == null))
                {
                    var template = new StringBuilder();

                    if (controllerAction.Controller.ControllerName != "Home")
                    {
                        template.Append(PascalToKebabCase(controller.ControllerName));
                    }

                    if (controllerAction.ActionName != "Index")
                    {
                        template.Append("/" + PascalToKebabCase(controllerAction.ActionName));
                    }

                    selector.AttributeRouteModel = new AttributeRouteModel()
                    {
                        Template = template.ToString()
                    };
                }
            }
        }

        public static string PascalToKebabCase(string value)
        {
            if (string.IsNullOrEmpty(value))
                return value;

            return Regex.Replace(
                value,
                "(?

Then registering it in Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddMvc(options => options.Conventions.Add(new DashedRoutingConvention()));
}
