Error: A native exception has occurred in SQLCompact 3.5 under Windows Embedded Compact 7

Hi,I have developed an application using Visual Studio 2008 on C# for stand-alone device, working under Windows Embedded Compact 7. Application work with SQLCompact 3.5 .
using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.SqlServerCe;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace TestSQLCompact
{
PublicpartialclassForm1 : Form
{
Publicstring open_db = "Data Source=Test7.sdf";
PublicSqlCeConnection conn;
Publicstring query_list;

    public Form1()
    {    
        InitializeComponent();
        conn = newSqlCeConnection(open_db);
    }

    Private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            conn.Open(); 
        }
        catch (SqlCeException se)
        {                
            return;
        }
        query_list = "SELECT * FROM Rashod";
        DataSet ds = newDataSet();
        SqlCeDataAdapter da = newSqlCeDataAdapter(query_list, conn);
        da.Fill(ds);
        . . .
        conn.Close();        
    }  
}

}
I started application under Debugger of Visual Studio 2008 and at string
da.Fill(ds);
I get Error : A native exception has occurred in TestSQLCompact.exe
Detail message:
Error
ExceptionCode: 0xc0000005
Exception Address : 0
Reading: 0

When I made the same application for Windows 7, it is running without any error.
Also I made next steps:

1. Added new Ites to Project - seven SQL Server Compact 3.5 DLLs:
   sqlceca35.dll , sqlcecompact35.dll , sqlceer35EN.dll , sqlceme35.dll,
   sqlceoledb35.dll , sqlceqp35.dll , sqlcese35.dll .
2. For each of these DLLs in Solution Explorer opened the Properties window.Then set the Copy to Output Directory property to Copy if newer.
3. In Solution Explorer expanded Reference node, selectedSystem.Data.SqlServerCe and set the Copy Local property to True.
   But result not changed. I searched in other forums, but without result.
