That is not true, you are reading too much into that post. We have no intentions of releasing a new version of Prism for Windows Runtime targeting Windows 8/8.1 only unless people submit issues to our repo (http://github.com/prismlibrary
that warrant attention. And if they do, we encourage the community to pitch in and help develop those new features. And what we expect to do post Build will be an evolution of Prism for Windows Runtime and will hopefully be backward compatible for Windows
8 apps. We will have to see when we build that backlog.
But we definitely encourage people to submit issues or feature requests against the Prism for Windows Runtime code base to help guide what we decide to do there. Prism for Windows Runtime is definitely not dead either. We are just not immediately focusing on
it because we want whatever we do with it to be guided by where Windows Runtime is going under Windows 10. Windows 10 is still a WinRT-based programming model, so it should be an evolution of the current universal apps code. But one intention we already have
even if we don't add any new features is to clean up that code base - the 2.0 release seems to have been put together in a bit of a hurry by the p&p team and is a little confusion on the organization (i.e. three different versions of the .StoreApps library
in there) - so at a minimum we will be doing some clean up there.
If you have specific issues or things you would like to see done with it, please submit issues against our GitHub repo.
