I'm using a portable library class and I'm targeting to .NET 4.5, Silverlight 5 and Windows Store apps.
According to MSDN, it's possible to use MEF in these three plattforms: http://msdn.microsoft.com/en-us/library/gg597391.aspx
But I can't accomplished to use MEF in these plattforms. What is the correct way to use MEF in PCL?
The documentation is incorrect. MEF was originally available in the box for Store apps, but due to a variety of reasons it was pulled before RTM. Currently, we have a newer version of MEF available between .NET 4.5 and Store apps (https://nuget.org/packages/microsoft.composition) but not between Silverlight, .NET and Store apps.
It's something we're considering for a future version. If you feel its important, can you file a suggestion over on uservoice: http://visualstudio.uservoice.com/forums/121579-visual-studio/category/31481-net. Customer feedback/requests are weighted heavily when determining what we work on next.
