Share project between Windows Store Application And WCF Service

Question

Is it possible to create and "share" a class library project between an Windows Store Application and WCF Service project ?

I created Windows Store Application project and WCF Service project. Now, both projects should refer a Class library project.

If I create a regular Class Library project, the WCF Service project can refer it. But when I add the reference to the Windows Store Application Visual Studio 2012 says :

Unable to add the reference to project XXX

So I decided to replace the regular Class Library project by a Class Library(Windows Store apps). Now the Windows app project can refer the Class Library(Windows Store apps). But when I add the reference to the WCF Service Visual Studio says :

Unable to add the reference to project XXX

Answer 1

To share code between the two projects create a Portable Class Library (PCL) project and reference it in the two projects.

Make sure you choose the right .Net framework (for compatibility with WCF project).
