This release contains the required binaries to create your own applications, and also the complete source code of the library and all included samples. The Windows Phone application "PAARC" that has been accepted by Microsoft into the Marketplace (http://windowsphone.com/s?appid=c094fd13-3771-4bf9-b546-83c482f293f2) is based on this source code, hence it is considered stable.

More information on this release can be found in the blog post here:
PAARC - Milestone reached

Note: After upgrading to TFS from Mercurial, changeset 24422 will not produce the exact same output as included in the binaries download because dependent NuGet packages have been upgraded since then. If you need an identical repro of version 0.9 use the source code package download instead of the change set content.
