I was followed the steps and i was added one entity in model and also create entityset and business logic class but i was run the program an error occure in NopObjectContext and my site give an error.

  public ObjectSet<CustomerSession> CustomerSessions
        {
            get
            {
                if ((_customerSessions == null))
                {
                    _customerSessions = CreateObjectSet<CustomerSession>();======> Error in this line
                }
                return _customerSessions;
            }
        }

Error : Schema specified is not valid. Errors:
The relationship 'NopSolutions.NopCommerce.BusinessLogic.Data.FK_Nop_TierPrice_Nop_ProductVariant' was not loaded because the type 'NopSolutions.NopCommerce.BusinessLogic.Data.TierPrice' is not available.
The following information may be useful in resolving the previous error:
The required property 'DiscountRate' does not exist on the type 'NopSolutions.NopCommerce.BusinessLogic.Products.TierPrice

I am also facing the same problem

any help will be appreciated.

I also met this problem like you. Can you hellp me?

I just added an other entity model and used that where needed, it works for me.

modifying the existing data model is the real pain, I recommend its better to add an other entity model and used new one where needed.
