How to make a nullable property in EF Codefirst?

Question

I have two POCOs in my \"Bookshelf\" test application:

/// 

/// Represents a book
/// 
public class Book
{
    public int ID { get         


        

Answer 1

Couldn't you just use something like this

public virtual Nullable LoanedTo { get; set; }

That then should make LoanedTo a nullable property
