EF5 How to get list of navigation properties for a domain object

Question

I\'m working on an EF 5 Code-First solution and I am trying to update an existing entity with a modified one using the Repository pattern:

    public void Up         


        

Answer 1

Ah, the glories of LINQ (and using):

public List GetNavigationProperties(T entity)
{
    var t = entity.GetType();
    var elementType = ((IObjectContextAdapter)context).ObjectContext.CreateObjectSet().EntitySet.ElementType;
    return elementType.NavigationProperties.Select(np => entityType.GetProperty(np.Name)).ToList();
}

This can also be implemented via a static method, with the following signature:

public static List GetNavigationProperties(DbContext context)
{
    var t = typeof(T);
    ...
