здесь лежит проект, к-рый выстреливает assert на таком коде:

Imports System
Imports System.Collections.Generic

Imports BLToolkit.Data
Imports BLToolkit.Data.Linq
Imports BLToolkit.DataAccess
Imports BLToolkit.Data.Sql.SqlProvider
Imports BLToolkit.Data.DataProvider

Imports System.Data.SQLite


Module Module1

    Sub Main()
        Dim CONNECTION_STRING_TEMPLATE As String = "Data Source={0};Synchronous=Full;"
        Dim cnsOffline As String = String.Format(CONNECTION_STRING_TEMPLATE, "C:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\Projects\BLToolkitTest4\BLToolkitTest4\Backdrop.db")
        Using dbmBackdrop As New GroupCalendarDBManager(New SQLiteDataProvider(), cnsOffline)
            Dim oSrcFromB = (From a In dbmBackdrop.Appointments _
                              Where Not a.IsDeleted And a.ByDelegateFrom = "11" _
                              And (a.UpdateStatus = UPDATESTATUS.Accepted Or a.UpdateStatus = UPDATESTATUS.UpdateForOwner Or a.UpdateStatus = UPDATESTATUS.SubmittedToOnline) _
                              Select a).ToList()
            Debug.Assert(oSrcFromB.Count = 0)
            '            Console.WriteLine(s)
            '            Console.ReadKey()
        End Using
    End Sub
End Module

bltoolkit последний. В чем причина такого косяка?
