Why is recovering cookies (from Json) in CefSharp not working as it should?

Question

C++ / C#

Saving cookies

void SaveCookies()
        {
            var cv = new CookieVisitor();
            Cef.GetGlobalCookieManager().VisitAllCookies(cv);
            var json = JsonConvert.SerializeObject(cv.Cookies);
            File.WriteAllText(settingsPath, json);
        }

Restoring cookies

void SetCookies()
        {
            var json = File.ReadAllText(settingsPath);
            var cookies = JsonConvert.DeserializeObject<List<Cookie>>(json);

            if (cookies == null || cookies.Count == 0)
                return;

            foreach(var cookie in cookies)
            {
                Cef.GetGlobalCookieManager().SetCookie(cookie.Domain, cookie);
            }
        }

CookieVisitor

class CookieVisitor : ICookieVisitor
    {

        public List<Cookie> Cookies { get; set; }

        public CookieVisitor()
        {
            Cookies = new List<Cookie>();
        }

        public void Dispose()
        {
            
        }

        public bool Visit(Cookie cookie, int count, int total, ref bool deleteCookie)
        {
            if (cookie == null)
                return false;

            Cookies.Add(cookie);
            return true;
        }
    }

When a cookie is restored, the browser does not restore the session.
For
Cef.GetGlobalCookieManager().VisitAllCookies(cv);
some reason, the input goes directly to cv.Dispose() on the line.
What am I doing wrong?

Answer 1

You need to set CachePath to save all local data instead of storing cookies separately. If CachePath is not set, closing the browser deletes all local data.
