SQL Server CE 3 Constraint Problem

SQL CE 3.0
I am trying to add constraints using SQL statements but get an error saying that the constraint would cause a cyclical reference. The same statements work with SSCE 2.0

Eg
CREATE TABLE A(pkA integer NOT NULL CONSTRAINT pkAx PRIMARY KEY);

CREATE TABLE B(pkB integer NOT NULL CONSTRAINT pkBx PRIMARY KEY,
pkA integer NOT NULL,
CONSTRAINT fkBA FOREIGN KEY (pkA) REFERENCES A(pkA) ON DELETE CASCADE ON UPDATE CASCADE);

CREATE TABLE C(pkA integer NOT NULL, pkB integer NOT NULL,
CONSTRAINT fkCA FOREIGN KEY (pkA) REFERENCES A(pkA) ON DELETE CASCADE ON UPDATE CASCADE,
CONSTRAINT fkCB FOREIGN KEY (pkB) REFERENCES B(pkB) ON DELETE CASCADE ON UPDATE CASCADE);

I dont see that the foreign keys should cause a cyclical reference problem.

I have also tried not having the ON UPDATE DELETE on one of the Constraints on Table 3.

Any ideas anyone would be appreciated.
