• Download LightSwitch Beta 2 (MSDN Subscribers with Visual Studio 2010)
• Thursday's 10:00 AM PDT general availability download will be here.

Please see “What’s New in Beta 2” for information on new capabilities, installation options, and compatibility notes for this release. Unfortunately, due to the many improvements in Beta 2, projects created in Beta 1 cannot be opened or upgraded. You can find instructions for moving your existing projects forward on the LightSwitch team blog.

We are happy to announce that Beta 2 comes with a “Go Live” license which means you can now start using Visual Studio LightSwitch for production projects!

Since the launch of Beta 1, the team has been heads down in working through your feedback and has made some improvements that I think you’ll agree are pretty cool.

• Publish to Azure: the Publish Wizard now provides the ability to publish a LightSwitch desktop or browser application to Windows Azure, including the application’s database to SQL Azure. The team is planning a detailed tutorial of this experience that will get posted on the team blog later this week.
• Improved runtime and design-time performance: Build times are 50% faster in Beta 2 and we have made the build management smarter to improve iterative F5 scenarios by up to 70%. LightSwitch Beta 2 applications will startup up to 30% faster than Beta 1. New features like static spans will include related data in a single query execution and improve the time to load data on a screen by reducing the total number of server round-trips. The middle tier data load/save pipeline has been optimized to improve throughput by up to 60%.
• Runtime UI improvements: Auto-complete box, better keyboard navigation, and improved end-user experience for long-running operations.
• Allow any authenticated Window user: When Windows authorization was selected in a LightSwitch app, you previously needed to add the Windows users who are allowed to use the application into the User Administration screen of the running application. This is cumbersome in installations where there are a large number of Windows users and when you just wanted to open the app up to all Windows users. The project properties UI now allows you to authenticate any Windows user in a LightSwitch application while still using the LightSwitch authorization subsystem for determining user permissions for specific users.
