The developer preview version of Windows Phone 8.1 was released to developers on Monday morning. 
Cliff Simpkins, product manager for Windows and Windows Phone developer experience at Microsoft, announced the release in a blog entry. Simpkins noted that the   Windows Phone Store is starting to take app submissions and enable app    linking, which allows  apps to work across different Windows 8 devices, from desktops and laptops, to tablets and phones (and, eventually, Xbox). 
Microsoft announced and previewed these "universal   Windows apps" at the Build conference earlier this month.
 The developer preview version of Windows Phone 8.1 is important for    developers since some aspects of apps need to be tested on  real   devices,  rather than just an emulator. Simpkins, for example, wrote that   he uses an  emulator for testing whether the code works properly, while   using the app on a  working Windows Phone provides valuable information   about an "app's real-world  usability (e.g., touch target sizing, load   times)."
 As a supplement to the Windows Phone Preview for Developers,  MSDN published a reference  app to help developers learn how to integrate their apps with Cortana, the    new voice assistant that's also part of Windows Phone 8.1. The app,   called MSDN  Voice Search, provides voice-enabled search capabilities to   documentation and  source code for building Cortana functionality into   new or existing apps.
 There are a few requirements to get the Windows Phone  Preview for   Developers. A developer either needs to register as a Windows Phone    developer, which costs $19 annually, or register as a developer with App   Studio,  which is free. The other option is to download the developer   tools to register  and "developer unlock" a Windows Phone (Microsoft provides  instructions on how to do this).
