How to create a portable library class targeting Windows Phone 8 without installing the Windows Phone 8 SDK?

Question

I would like to create a portable library class targeting Windows Phone 8 from a Windows 2008 R2 machine with Visual Studio 2010 on it and without Windows Phone 8.0 SDK installed.

From Visual Studio 2010, there are only these options available:

Is there a multi-target package for Visual Studio to install that supports Windows Phone 8 target framework?

Note:
Since Windows Phone SDK 8 requires Windows 8, it can't be installed on this kind of development workstation (back-end oriented).

Answer 1

I think it is not possible. WP8 requires VS2012 and Windows 8. I got the same problem in the past.

Answer 2

You don't need the WP8 SDK specifically. The simplest thing to do would be to use Visual Studio 2012 Update 2 or later. You may also be able to install a later version of the Portable Library Tools for VS 2010 to get most of the PCL WP8 support.
