  • How do I use the Windows API Code Pack in VB.net 2010 Express?

    - by Josh
    Hi all, I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources. Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?
