ASP<span></span>.NET Core provides cookie middleware which serializes a user principal into an encrypted cookie and then, on subsequent requests, validates the cookie, recreates the principal and assigns it to the
Userproperty onHttpContext.References:

Thanks @aaron for your help. Have checked the IMayHaveTenant documentation.
I have one last question to that.
How does this affect performance? To use a filter it means whenever i request something from database using IRepository it intercepts request and adds TenantId. IMHO this results in performance penalty opposed to do it manually when requesting it (x.TenantId = user.TenantId)

aaron I still dont understand how IMustHaveTenant works. Tried to read the documentation but it does not say much apart from
IMustHaveTenant defines the TenantId property to distinguish between different tenant entities. ASP.NET Boilerplate uses the IAbpSession to get the current TenantId by default and automatically filters the query for the current tenant.How does it work with Update and Insert methods. Cant find any example. Do I need to set TenantId when updating or inserting or IMustHaveTenant does it automatically? Also If I set it manually does IMustHaveTenant checks if that TenantId is the correct one when updating a record? -

ABP sets
TenantIdforIMustHaveTenantbut not forIMayHaveTenant.Also If I set it manually does IMustHaveTenant checks if that TenantId is the correct one when updating a record?
No, ABP does not check since it may be intended.
The documentation describes the behaviour. If you want to know every detail about how it is implemented, then you can read the source code. Both ABP and EF Core are open source.

This is my code:
[Table("TestOrder")] public class Order : Entity<long>, IMustHaveTenant { [Required] public string Name { get; set; } public string Description { get; set; } ..... [ForeignKey("TenantId")] public Tenant Tenant { get; set; } public int TenantId { get; set; } } [HttpPost] [AbpAuthorize(AppPermissions.Pages_Orders_Edit)] public async Task UpdateOrder(OrderInputDto input) { Order order = ObjectMapper.Map<Order>(input); await ordersTypeRepository.UpdateAsync(order); }and this is the error that I get:
