Could not load file or assembly or one of its dependencies. An attempt was made to load a program with an incorrect format. in VB.NET 2010

Could not load file or assembly 'Interop.PortableDeviceApiLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. ?

Today, I wanted to add PortableDeviceApiLib assembly to my project to pull some information from a iPhone device. After I add reference to the dll. I started getting this issue. To fix this you need to change the Platform to x86

Project Properties> Build > Target Platform to "x86"

strange solution, but it works.
