    hi

    You need copy the following code to the zero.

    https://github.com/IdentityServer/IdentityServer4/blob/main/src/IdentityServer4/host/Extensions/SameSiteHandlingExtensions.cs https://github.com/IdentityServer/IdentityServer4/blob/main/src/IdentityServer4/host/Startup.cs#L43 https://github.com/IdentityServer/IdentityServer4/blob/main/src/IdentityServer4/host/Startup.cs#L113

    Hi

    You can put the SameSiteHandlingExtensions in the Web.Core layer. Call AddSameSiteCookiePolicy and UseCookiePolicy in Startup class of Web.Mvc or Web.Host

    I think you need to improve on replying to customers. Late and short answers aren't enough for everyone. For example your latest reply is a short one. In your place I would have ussued this as a patch to make sure customers get good service.

    1. Step : Create new file on '/src/xxx.Web.Mvc/Startup/SameSiteHandlingExtensions.cs' The Code:

    `public static class SameSiteHandlingExtensions { public static IServiceCollection AddSameSiteCookiePolicy(this IServiceCollection services) { services.Configure

        private static void CheckSameSite(HttpContext httpContext, CookieOptions options)
    {
        if (options.SameSite == SameSiteMode.None)
        {
            var userAgent = httpContext.Request.Headers["User-Agent"].ToString();
            if (!httpContext.Request.IsHttps || DisallowsSameSiteNone(userAgent))
            {
                // For .NET Core < 3.1 set SameSite = (SameSiteMode)(-1)
                options.SameSite = SameSiteMode.Unspecified;
            }
        }
    }

    private static bool DisallowsSameSiteNone(string userAgent)
    {
        // Cover all iOS based browsers here. This includes:
        // - Safari on iOS 12 for iPhone, iPod Touch, iPad
        // - WkWebview on iOS 12 for iPhone, iPod Touch, iPad
        // - Chrome on iOS 12 for iPhone, iPod Touch, iPad
        // All of which are broken by SameSite=None, because they use the iOS networking stack
        if (userAgent.Contains("CPU iPhone OS 12") || userAgent.Contains("iPad; CPU OS 12"))
        {
            return true;
        }

        // Cover Mac OS X based browsers that use the Mac OS networking stack. This includes:
        // - Safari on Mac OS X.
        // This does not include:
        // - Chrome on Mac OS X
        // Because they do not use the Mac OS networking stack.
        if (userAgent.Contains("Macintosh; Intel Mac OS X 10_14") &&
            userAgent.Contains("Version/") && userAgent.Contains("Safari"))
        {
            return true;
        }

        // Cover Chrome 50-69, because some versions are broken by SameSite=None, 
        // and none in this range require it.
        // Note: this covers some pre-Chromium Edge versions, 
        // but pre-Chromium Edge does not require SameSite=None.
        if (userAgent.Contains("Chrome/5") || userAgent.Contains("Chrome/6"))
        {
            return true;
        }

        return false;
    }
}`
    1. Step : Change (add) '/src/xxx.Web.Mvc/Startup/Startup.cs' like this :

    Hi, I have done the same direction above, and login functionality is still elusive. Any other setup we need to do to get this through?

    Same here. I have not been able to login at all on v8.7.0. Are the latest versions working, meaning did you incorporate the SameSite fix into them? If I have to upgrade, I will have to.

    Hi, Thank you so much for the reply. I have followed as you instructed. SameSiteHandlingExtension.cs

    Web.Mvc

    Web.Host

    I even tried commenting the env.IsDevelopment condition as per @serdar said, but to no avail. I am not really sure what to do at this point as we cannot start anything without resolving it first. Thank you very much.
