Answer 1

'IApplicationBuilder' does not contain a definition for 'UseCookieAuthentication' and no accessible extension method 'UseCookieAuthentication' accepting a first argument of type 'IApplicationBuilder' could be found (are you missing a using directive or an assembly reference?)

请注意，UseCookieAuthentication 方法已过时。它似乎已从 ASP.NET Core 3.0 及更高版本中删除。

您可以在 ConfigureServices 方法中使用 AddAuthentication().AddCookie 配置 cookie 身份验证。

此外，这篇文档介绍了如何配置和使用cookie认证，您可以参考。
