QuestionWhat kind of relation is created with virtual keyword in EF Pin
Tridip Bhattacharjee2-Sep-16 2:46

I am new in EF. I mostly use ADO.Net to interact with DB. So learning EF code first.

Just see a below code. Post and blog class which has one-to-many relation I guess...........am I right?
C#
public class Blog 
{ 
    public int BlogId { get; set; } 
    public string Name { get; set; } 

    public virtual List<Post> Posts { get; set; } 
} 

public class Post 
{ 
    public int PostId { get; set; } 
    public string Title { get; set; } 
    public string Content { get; set; } 

    public int BlogId { get; set; } 
    public virtual Blog Blog { get; set; } 
} 


why blog class has one virtual property list type of Post?

And same way why post class has one virtual property type of Blog?

if we remove the virtual keyword only then what will happen?

how virtual keyword create relation?

why virtual keyword has been used in two class?

Please answer my all questions point wise in details.
