"Unable to cast object of type 'ProfileCommon' to type 'preferences.UserProfile" . I am really don't have any idea, because i m new to this project and i have no idea about this profile and all, So could you guys hep to get the answer

Code :

Public Shared Function GetUserProfile(ByVal username As String) As UserProfile
'Return TryCast(Create(username), UserProfile) - here i am getting the Error or Nothing as a result
End Function

Note : if i use direct cast or Type Cast it throws that error.
