Parameterized Insert - Changed Between 3.5Beta2 And 3.5RTM?

I'm hoping this is something obvious that I've missed...

The following code works fine using 3.5 Beta2 (System.Data.SQLServerCE.dll version 3.5.5365.0)

Using 3.5 RTM (System.Data.SQLServerCE.dll version 3.5.5386.0) it throws an error because it appears that the engine requires the input parameters to be either a) referenced by name or b) if not named, the Input parameters and INSERT columns statement must be in the same order as the actual table structure.

Error is "Cannot convert DateTime to UniqueIdentifier" - So I'm assuming its trying to stick the Parameters(1) value into [Col1], the UniqueIdentifier column.

Example uses this Table

CREATE TABLE Table1(

[ID] [int] NULL,
[Col1] [uniqueidentifier] NULL,
[Col2] [datetime] NULL)








Code Block Sample - Works in 3.5 BETA 2 - Fails in RTM

Dim cmd As New SqlServerCe.SqlCeCommand
Dim conn As New SqlServerCe.SqlCeConnection
conn.ConnectionString = "Data Source=e:data est.sdf"
Try
With cmd
.Connection = conn
.CommandType = CommandType.Text
.CommandText = "INSERT INTO [Table1] ([ID], [Col2], [Col1]) VALUES (?, ?, ?)"
.Parameters.Add(New SqlServerCe.SqlCeParameter("ID", System.Data.SqlDbType.Int))
.Parameters.Add(New SqlServerCe.SqlCeParameter("Col2", System.Data.SqlDbType.DateTime)) .Parameters.Add(New SqlServerCe.SqlCeParameter("Col1", System.Data.SqlDbType.UniqueIdentifier))
.Parameters(0).Value = 1
.Parameters(1).Value = Now .Parameters(2).Value = "{17F453BA-03F0-4d10-B015-0BADC7DD2471}"
.Connection.Open()
.ExecuteNonQuery()
.Connection.Close()
End With
Catch ex As Exception
MessageBox.Show(ex.Message)
Exit Sub
End Try
MessageBox.Show("Success")
If we change "INSERT INTO [Table1] ([ID], [Col2], [Col1]) VALUES (?, ?, ?)" to
"INSERT INTO [Table1] ([ID], [Col2], [Col1]) VALUES (@ID, @Col2, @Col1)" it works

Or swap the order of parameters added to the collection and use
"INSERT INTO [Table1] ([ID], [Col1], [Col2]) VALUES (?, ?, ?)" , this works.

Did something change between Beta2 and RTM that now would dissallow the code listed in our Sample?

Thanks,
