Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request

I know maybe its too late but I just wanted to comment. If you still having this issue, make sure that you have same FacebookCallBack method name everywhere. I mean, for instance I have an External Login function which returns ;

https://www.facebook.com/dialog/oauth?client_id=" + FB_APP_ID + "&redirect_uri=" + System.Net.WebUtility.UrlEncode(pageUrl + "account/**FacebookLoginCallback**?returnUrl=%2F").Replace("%3F", "&") + "&scope=email&enforce_https=1

and also I have a FacebookLoginCallback method which has exactly the same name with I have above. ("account/FacebookLoginCallback?....")

[HttpGet("**FacebookLoginCallback**")]
public async Task<IActionResult> **FacebookLoginCallback**(string code, string returnUrl)
        {
            try
            {
                var myUrl = new Uri(HttpContext.Request.GetDisplayUrl()).GetLeftPart(UriPartial.Authority);
                var pageUrl = new UriBuilder(myUrl);
                var result = (IDictionary<string, object>)fb.Get("oauth/access_token", new
                {
                    client_id = FB_APP_ID,
                    client_secret = FB_APP_SECRET,
                    redirect_uri = pageUrl.Uri.AbsoluteUri.TrimEnd('/') + Url.Action("**FacebookLoginCallback**", "Account", new { returnUrl = returnUrl }),
                    code = code
                });
       }

......
}

Please double check your variable/function names if you have those in your url.

Happy Coding

First, both redirect_uri paramaters to authorize and access_token must match.
