The CustomRouteHandler does not work after Upgarde

[jasmeetsangari]

Hi,

We Upgraded to the AR Version 3.5.6 from 3.4 and Now the CutsomRouteHandler Stoped Working. We ere registering the RouteHandler through the Property UseRouteHandler

routes.MapHttpAttributeRoutes(config =>
{
config.AddRoutesFromAssemblyOf();
config.AttributeRouteFactory = new AttributeRouteFactory(config);
config.AutoGenerateRouteNames = true;
config.UseRouteHandler(() => new CustomHttpControllerRouteHandler());
});

That does not work anymore
