Probably something simple, but as I'm new to lambda expressions, the problem evades me:

m => m.contactID == contactID && m.primaryAddress == true && (m.addressTypeID == 2 || m.addressTypeID == 3)

I tried to use that lambda expression but I receive an invalid operator. Is there a way to simplify this so that it would work?

Edit:

The equivolent sql query would be:

SELECT *
FROM Contact
WHERE contactID = 3
AND primaryAddress = 1
AND (addressTypeID = 2 OR addressTypeID = 3)

I have a repository function defined like so:

public E Single(Expression<Func<E, bool>> where)
{
    return objectSet.Single<E>(where);
}

I'm passing the lambda expression above into this function. Invalid operator error.
