In Visual Studio Update 2 How Can I Disable PCL Automatically Targeting Windows Phone 8 When I've Selected Windows 8

Prior to Visual studio update 2 I could create a Portable Class Library PCL that targeted .Net Framework 4 or 4.5 and also Windows 8.

After the update Windows Phone 8.1 is automatically targeted when you select Windows 8.

Problem I have is Entity Framework is not compatible with Windows Phone, so previously created PCL targeting .Net Framework and windows 8 that included Entity Framework nuget package no longer builds.
