New Post: Nuget wont install MVVMLight Portable Libs

Hi,

I'm trying to install MVVMLight Portable into one of my PCL using Visual Studio 2013. However, whenever I try install it via the package manager console (IE. install-package portable.mvvmlightlibs) I get the following error :

install-package : Could not install package 'Portable.MvvmLightLibs 4.2.30.1'. You are trying to install this package into a project that targets 'portable-net45+sl40+wp80+win', but the package does not contain any assembly references or content files that 
are compatible with that framework. For more information, contact the package author.

Do you possibly know what I'm doing wrong/missing?

Thanks
