Another alternative I have discovered is to use a shared member property of a Helper object to hold the collection that needs to be searched.

I can define this as follows:
Public Class ATBusinessInfoHelper

    Private Shared _userContainer As AUSObservableCollection(Of ATUser)

    Public Shared Property UserContainer() As AUSObservableCollection(Of ATUser)
        Get
            If _userContainer Is Nothing Then
                Throw New AUSException("UserContainer has not been defined")
            Else
                Return _userContainer
            End If
        End Get
        Set(ByVal value As AUSObservableCollection(Of ATUser))
            _userContainer = value
        End Set
    End Property
End Class


Then in the IDataErrorInfo validation logic, I can step through ATBusinessInfoHelper.UserContainer to see if there is a conflict with an existing name. Would this be a valid approach to take?

Thanks for any advice,
Tim
