(VS 2005) SQL Compact Connection

[wiadus]

I would be most grateful if anybody could help with sql server 2005 compact edition connection string and also when I use imports system.data.sqlserverce I get errors. I am new to mobile developing so I need help badly. Below is what I am trying to do but to no avail.

Imports System.Data
Imports System.Data.sqlServerCe

Public Class ShiftManagerDB

    Public Shared Function GetConnected() As SqlServerCe       
 Return New SqlServerCe(GetConnectionString)
    End Function

    Public Shared Function GetConnectionString() As String
        GetConnectionString = "Data source=my documents\ShiftManagerPro.sdf;persist security info=False;"
    End Function

End Class

The SqlServerCe is always underline as error.
I am using this class in a windows app that I am coding for mobile.
