框架 4.8 的 web.config Asp.net Web 项目中不允许使用“sameSite”属性

Question

I been trying to add sameSite = None attribute to my project cookies as a part of Chrome standards. I am using .net framework 4.8 and it supports sameSite for cookie ( https://learn.microsoft.com/en-us/as.net/samesite/system-web-samesite#using-samesite-in-as.net-472-and-48 ), but i am not able to do it from web.config Please help if anyone has faced similar problem and resolved that.

Answer 1

This is only a warning because the attribute isn't included in Visual Studio yet. It shouldn't stop you compiling and will work in production because the latest browsers support it.

As Microsoft includes this in their official documentation I would use it as recommended and ignore the warning until an update is released with the same site parameter included.

<configuration>
 <system.web>
  <httpCookies sameSite="[Strict|Lax|None|Unspecified]" requireSSL="[true|false]" />
 <system.web>
<configuration>

As of Visual Studio Community 2022 Version 17.0.6 this is still not included.

(It might be safe to assume this will never get added to Visual Studio.)

Answer 2

chrome://flags/#same-site-by-default-cookies

Paste In Browser Url

Disable It

Now Working fine

samesite=None
