i have tried using ADO.NET Entity Data Model in my ArcDesktop project using dockable windows.

but every time i start debugging im getting a error.

COMException was unhandled by user code
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

Private Sub SetupDockableWindow()
        If m_dockableWindow Is Nothing Then
            Dim dockWindowManager As IDockableWindowManager
            dockWindowManager = CType(m_application, IDockableWindowManager)
            If Not dockWindowManager Is Nothing Then
                Dim windowID As UID = New UIDClass
                windowID.Value = regKey.GetValue("dwUID") 'DockableWindowGuid
                m_dockableWindow = dockWindowManager.GetDockableWindow(windowID) ' <-----on this line
            End If
        End If
End Sub

Add a Try...Catch with some error checking.  Or at minimum, step through and determine the exact line it is failing on.

have tried adding try catch... still getting an error in this line...

COMException was unhandled by user code
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

m_dockableWindow = dockWindowManager.GetDockableWindow(windowID) ' <-----on this line
