Blazor Server App with Dynamic CultureInfo Saved in Cookie don't work in iFrame anymore
Hi, I can't share my own app for nda issue but I found this one which shows exactly the same issue
https://github.com/tossnet/Blazor-Localization
This app displays a page with a CultureSwitcher component to select between 5 languages.
When you select a language, I can see both the page+dropdown refreshed with the selected language value.
Now, you embed the Url of this app inside a new app's page inside an iFrame and nothing works anymore.
The cookie mecanism doesn't save or/and load the value anymore.
This was working perflecly in net+core+3.1 and 5.0 but no more in net+core+6.
Is something change in security or cors or ????
Thanks in advance for any tips

Lan Huang- Hi,
it's all linked to enhancement of the browsers security stuff (specially Chrome and Edge); apparently, the old implement sill works in FF.
After getting help, the best practice to embed Url endpoints into iFrames is to follow this post from you guys : https://docs.microsoft.com/en-us/aspnet/samesite/system-web-samesite
In fact, I just had to add the last line to make it work:
HttpContext.Response.Cookies.Append(
CookieRequestCultureProvider.DefaultCookieName,
CookieRequestCultureProvider.MakeCookieValue(
new RequestCulture(culture)),
new CookieOptions() { SameSite = SameSiteMode.None, Secure = true} );
Hopes it will help people with same issue.
