Get the EntitySet name from an EntityType in EF

Question

Given an EntityType, such as \"Contact\", how can I derive from it the name of the EntitySet it would belong to, i.e. the pluralization such as \"Contacts\"?

This extension may be useful

public static class MyExtensions
{
    public static string GetEntitySetName(this ObjectContext context)
    {
        string className = typeof(T).Name;

        var container = context.MetadataWorkspace.GetEntityContainer(context.DefaultContainerName, DataSpace.CSpace);
        string entitySetName = (from meta in container.BaseEntitySets
                                where meta.ElementType.Name == className
                                select meta.Name).First();

        return entitySetName;
    }
}

And use it like:

db.AttachTo(db.GetEntitySetName(), myEntityInstance);
