Created Issue: windows phone 8 project support [16376]

Hello!
I have problem when trying to get NAudio from Nuget in my Windows Phone 8 project.
Here is log from console:
PM> Install-Package NAudio -Pre
Successfully installed 'NAudio 1.7-alpha01'.
Successfully uninstalled 'NAudio 1.7-alpha01'.
Install failed. Rolling back...
Install-Package : Could not install package 'NAudio 1.7-alpha01'. You are trying to install this package into a project that targets 'W
indowsPhone,Version=v8.0', but the package does not contain any assembly references or content files that are compatible with that fram
ework. For more information, contact the package author.
