Via extension method (for every ObjectContext):

internal static class ObjectContextExtensions
{
    public static bool IsContextDirty(this ObjectContext objectContext)
    {
        return objectContext
            .ObjectStateManager
            .GetObjectStateEntries(
                EntityState.Added | 
                EntityState.Deleted | 
                EntityState.Modified).Any();
    }
}

or via partial method (only for your ObjectContext):

partial class MyModel
{
    public bool IsContextDirty()
    {
        return ObjectStateManager
            .GetObjectStateEntries(
                EntityState.Added | 
                EntityState.Deleted |
                EntityState.Modified).Any();
    }
}
