I have two web application (Asp.net - VB) one in VS 2005 and another is in VS 2012 - Now I have to share session between these two applications. Session state actually maintain in VS 2005 (Old project) and both application are hosted on same IIS (7.0). When I access page from VS 2012 project I have to use same session which was generated in VS 2005 project at same time. Note: Both projects has same content, design, code etc. Can anyone as idea or solutions on the same?
