Problem with Mvc.RenderViewToString and Url.Action about entropy HOT 4 CLOSED

Currently there is no way of doing this if you need all the routing behavior to go with it. Since you have your own logic of url generation, you can just write your own implementations of IUrlHelperFactory and IUrlHelper and add it to services. You will get no routing magic there. You'll need to put your logic in the Action method, something like,

public class CustomUrlHelper : IUrlHelper
{
    public string Action(UrlActionContext actionContext)
    {
        return $"{actionContext.Protocol}://{actionContext.Host}/{actionContext.Controller}/{actionContext.Action}";
    }
    .
    .
    .
}

And just add services.AddSingleton<IUrlHelperFactory, CustomUrlHelperFactory>(); in Program.cs

@Eilon Could you triage/assign?

@Bartmax, this is not a limitation. This is expected. This sample was added to demonstrate rendering a view to a string given a model. It does not involve any controllers or actions. This isn't meant for that. Both Url.Action() and AnchorTagHelper need actions and controllers to be present. So you can't use them here.

I understand, thanks for your explanation.

I'm using this to create email html from models. In the same project I do have controllers and actions, that's why I want to use something like <a asp-controller="Home" asp-action="Help">help</a> but I also need them to be absolute not relative; //domain.com/Help instead of /Help.

Is there any sample that shows how to make it work with controller/actions or any guidance on what must be done/added ?

currently I'm doing logic on the ViewModel to get the url, maybe that's a reasonable way to do it ?
