There are two types of authentication, cookie and bearer. Where the cookie keeps you logged in, the bearer token can’t.

Attribute [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)] public sealed class CannotBeRedAttribute : ValidationAttribute, IClientModelValidator { public override bool IsValid(object value) { var message = value as string; return message?.ToUpper() == “RED”; } public void AddValidation(ClientModelValidationContext context) { MergeAttribute(context.Attributes, “data-val”, … Read more

You have to configure it in Startup.cs services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>(); services.TryAddSingleton<IActionContextAccessor, ActionContextAccessor>(); UPDATE: In ASP.NET Core 2.1, the AddHttpContextAccessor helper extension method was added to correctly register the IHttpContextAccessor with the correct lifetime (singleton). So, in ASP.NET Core 2.1 and above, the code should be services.AddHttpContextAccessor(); services.TryAddSingleton<IActionContextAccessor, ActionContextAccessor>(); Source: … Read more
