I have the following situation.
I developed my first MVC Asp.Net application. it runs on my server at the following adress
http://localhost:59441/
I know this is an old post. But, I had the same issue and ended up here. And managed to fix that issue with UrlHelper.Action method. It should be used something like this. (Note that this specific solution will works within the view.)
url: "@Url.Action("UpdateCheckBox", "CeduleGlobale")",
Hope this helps. :)
