Why EF6 not support ` ignore ` the property of the entity Property(complex property) Fluent API?

Question

if the entity as

public class AddressDetail 
{
   public string Country{get;set;}
}

public class Order
{
    public AddressDetail AddressDetail{get;set;}
}

How ignore the Oreder.AddressDetail.Country property by Fluent API Not [NotMap] ?

I found the solution for EF6 ，but I don't know Why Before EF6 have the function，EF6 don't have the function?

For EF5 and older: In the DbContext.OnModelCreating override for your context:

modelBuilder.Entity<Product>().Ignore(p => p.AddressDetails.Country);

For EF6: You're out of luck. See Mrchief's answer .

I understand this exception that only plain property expressions are allowed, so if you want to ignore the property of a property, you have to do it on the type of the outer property:

modelBuilder.Types<WhateverTheTypeOfResponseIs>()
    .Configure(c => c.Ignore(r => r.MobilePhone));

Though, i guess the proper syntax for EF6 would be:

modelBuilder.Entity<WhateverTheTypeOfResponseIs>()
    .Ignore(r => r.MobilePhone);
