I have updated my package with \lib\NET3.5
Unfortunately, I'm still getting the error message from Add-Package:
_WriteError : Unable to find assembly references that are compatible with the target framework '.NETFramework,Version=v3.5'
At C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\CodePlex Foundation\NuPack Tools\0.1\Scripts\nupack.ps1:107 char:24

I have unzipped the .nupkg to tripple check that it's folder is infact "lib\NET3.5".
Only if I change the projects target framework to .NET 4.0 does "Add-Package" work. Strange that the error above is infact referring to .NET 3.5, yet if I choose .NET 3.5 as the target framework for the project it's not happy with it.
