How To Create A Table Using SqlCeCommand?

VS2008 Express, SQL Server CE 3.5 SP2, Windows Forms desktop application

My code is like this:

SqlCeCommand command = new SqlCeCommand();
SqlCeConnection connection = new SqlCeConnection(@"Data Source=|DataDirectory|MyDBCE.sdf");
connection.Open();
command.CommandType = CommandType.Text;
command.Connection = connection;
string cmd = @"CREATE TABLE MyTable(
Id int NOT NULL,
Name nvarchar(50) NOT NULL,
X int NOT NULL,
Y int NOT NULL)";
command.CommandText = cmd;
command.ExecuteScalar();
connection.Close();

This code does not throw any error, so I presume it is doing something correctly.
However, after the application finishes, there is no table MyTable in this database.
If I run this code once again, it doesn't say that table MyTable already exists, so it does not exist.

Can someone tell me how to create a table in SQLCE ?
