How should I remove all elements in a DbSet?

Question

What\'s the best way to remove all elements in a System.Data.Entity.DbSet, with Entity Framework 4.3?

Answer 1

Here's another way you can do it in code.

public static class Extensions
{
    public static void DeleteAll(this DbContext context)
        where T : class
    {
        foreach (var p in context.Set())
        {
            context.Entry(p).State = EntityState.Deleted;
        }
    }
}

To actually call the method and clear the set:

myDbContext.DeleteAll();
