16. Demo: Q&A

17. Two IDEs
•
Visual Studio 2012/13
support with business
licence
•
Xamarin Studio is great too!
•
Development and build can
be separated

18. PCL vs Linked Files
•
PCL support (Profile158) is stable-ish
•
Try PCL until you can’t.
•
Plugins are easy to write
•
Existing codebase may not build under
PCL (e.g. XmlDocument or DataTable)
