I replaced ActionContext with ControllerContext, and it works for me. I don't know if it's an official migration step, though.

It provides a possible solution to Andrey Markovs' problem, as it was the solution for my problem that brought me here in the first place. I don't see how deleting my comment and downvoting it was productive - is it really better for this question to be unanswered?! – fran.tonkovic May 19 '16 at 09:54
@ManoDestra How does this not provide an answer? – Undo May 19 '16 at 14:46

"I replaced it with ControllerContext" - replaced what exactly? There's no code in this question nor sufficient explanation of how to resolve the issue. With some editing, it could be improved though :) – ManoDestra May 19 '16 at 19:44

This is the correct answer. It seemed clear, but "it" refers to the ActionContext property indicated in the question. So: replace ActionContext with ControllerContext in RC2. – Jeremy May 25 '16 at 12:35

It works because `ControllerContext` is a subclass of `ActionContext`. – Mariusz Jamro Jan 28 '19 at 20:48

You can inject IActionContextAccessor to your class. It provides access to the action context.

services.AddSingleton<IActionContextAccessor, ActionContextAccessor>();

Use it:

private readonly IActionContextAccessor actionContextAccessor

public FooController(IActionContextAccessor actionContextAccessor)
{
    this.actionContextAccessor = actionContextAccessor;
}

See this issue.

This is strange. I just upgraded my codebase to .net core 3.1 and after that, I started getting null for IActionContextAcessor (I had no issues with .net core 2.2). The issue was gone after I explicitly added the line you mentioned here. I wonder why this has anything to do with .net core 3.1.... Thanks. – hamiltonjose Apr 16 '20 at 23:45
This actually helped me resolve my other problem of passing the actionContextAccessor to my Service Layer – Nathan Aug 04 '21 at 19:39

In .NET core 3.1 at least, ControllerBase has a property Url that works as a UrlHelper so you don't have to make one yourself. https://stackoverflow.com/a/52537244/4172413

.net core migration users should use this solution instead. – Jawand Singh Feb 01 '22 at 08:32
