Answer

For IEnumerable, using Any() method is the fastest way to check if the object exists in the database. It only has to look at one iteration and will return as soon as it finds a match.

using (var context = new EntityContext())
{
    if(context.Customers.Any(c => c.CustomerID == 1))
    {
        //match
    }  
}
