AbpSession tenantid is not getting set

Question

I am using aspnetzero for my development in .net and angular. When I enable the multitenancy in my project than abpsession tenantid is not getting set. It is null. If I disable it than host tenant id is getting set, which I want to set in case of multitenancy enabled case also. Is there any other setting which needs to be done?

Tried using using (var uow =_unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew)) {

                using (_unitOfWorkManager.Current.SetTenantId(1))
                {
                    _dbContextProvider.GetDbContext().Database.OpenConnection();
                    uow.Complete();
                }
            }

1 is the host id but it is not working.
