Hi

I have created a complete code using EF code first approach .

but when i try to add controller using EF

i get the following error that :

unable to determine principal end of a assiciationbetween the types model.person and supplier. while in the designer the realtion ship between the person and supplier is 1 to 0..1

following is the code of both modals :

public class Supplier
    {
        public int ID { get; set; }
        public virtual Person Person { get; set; }
        public virtual ICollection<SupplierItem> Items { get; set; }

    }

 public class Person
    {
        public int ID { get; set; }
        public string FName { get; set; }
        public string LName { get; set; }
        public string Cnic { get; set; }
        public string Contact { get; set; }
        public DateTime DateAdded { get; set; }
        public virtual Supplier Supplier { get; set; }
    }

I have also tried with virtual of supplier and person object in classes.

<pre lang="c#"><connectionStrings>
    <add name="cartModelContainer" connectionString="metadata=res://*/Models.cartModel.csdl|res://*/Models.cartModel.ssdl|res://*/Models.cartModel.msl;provider=System.Data.SqlClient;provider connection string="data source=SHAN\SHAN;initial catalog=Store;persist security info=True;user id=sa;password=123;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
