Windows Phone Developer Tools Beta Released

First things first: go get the Windows Phone Developer Tools Beta. It has arrived!

The term “Beta” is understood to mean that things are close to being finished.  Well, that’s what we mean anyway. This Beta release represents the near final version of the tools for building applications and games for Windows Phone 7. 

Since the initial CTP release of the tools just this March, the Windows Phone Developer Tool CTP has been widely embraced by the community, and they have shown what’s possible on our new development platform.

It’s time to get serious about building the actual apps and games for Windows Phone 7 that consumers will be looking for starting this holiday season.

One of the things I really want to do is just take a step back and congratulate the entire Windows Phone 7 team.  They have done an amazing job of delivering code month after month on our path to releasing later this year.  Check out this timeline:

  • Feb 2010 – Windows Phone 7 was unveiled at Mobile World Congress in Barcelona
  • Mar 2010 – The application platform was unveiled at MIX 10 in Las Vegas.  With that, we had the first CTP of the Windows Phone Developer Tools.
  • Apr 2010 – The tools received an updated, and the CTP Refresh shipped.
  • Jun 2010 – Windows Phone Marketplace details unveiled at TechEd 2010.  Get the Windows Phone 7 Application Certification Requirements.
  • July 2010 – Beta release of Windows Phone Developer Tools, and the preview developer phones start shipping to ISVs

Whew! The Windows Phone engineering team has been crushing it.

Here’s a link to the release notes for the beta, but I wanted to talk about a few top level items:

  • Microsoft Expression Blend for Windows Phone – Blend is now integrated completely into the Windows Phone Developer Tools Beta.
  • Developer Registration Utility – Now you can unlock you Windows Phone 7 device for development purposes.
  • XAP Deployment Tool – if you want to deploy XAP files directly to an unlocked device, now you can.
  • The Windows Phone 7 API – we’re getting close to completion.  Many namespaces that were previously distributed over several different DLLs have now been consolidated into one.  In addition, there have been realignments and changes in several other namespaces as well.  Push Notifications, Accelerometer and App Bar APIs have all been updated.
  • Additional Controls – There are some additional controls coming in the next few weeks (i.e. Panorama and Pivot) which didn’t make the beta release.  They are coming soon.
  • Control Templates – Silverlight for Windows Phone control templates have been updated to match evolutions in the overall OS.

Get Trained – Windows Phone 7 Jump Start

Windows Phone 7 JumpStart is a FREE virtual live class for developers interested in developing applications and games for Windows Phone 7.  We’re providing this in partnership with our MS Learning team. The course is organized into four virtual instructor-led sessions that are of 3-hour duration.  They will be presented by forthcoming MS Press authors and MVP’s, Andy Wigley and Rob Miles. It will provide developers a jump start for developing Windows Phone 7 applications.  The Labs will be completed offline with office hours access to the instructors.

The dates for these course sessions are:

  • July 20 – 8am: Session One: Getting Started with Microsoft Windows Phone and Silverlight
  • July 20 – 1pm: Session Two: Programming Game Applications with XNA
  • July 22 – 8am: Session Three:  Programming Applications with Silverlight
  • July 22 – 1pm: Session Four:  Review and Wrap Up

Devices for Developers

We made a promise last month that we would be getting pre-production preview devices to developers this month. We are keeping that promise. In fact, the very first preview devices were awarded last week to a pair of pretty amazing high-school students who won the Windows Phone “Rockstar” contest as part of the Imagine Cup. When we saw what they had done, we knew we had to get them preview phones.

Starting next Monday (July 19th), we start shipping the devices more broadly. Sadly, we will not be able to meet all of that demand.  We are planning to set up deploy and test labs in major cities to make it a little easier for everyone who wants to have access to a preview phone to have it. More on that soon.

Lastly, to get your name in the queue, assuming you haven’t already sent in an email, you can now send an email to [email protected].  A field representative will get back to you as soon as possible. Again, these are preview phones, so they are limited in quantity. When you send email, please include the following information:

  • Your name
  • Company name, if applicable
  • What city/state/country you are located in
  • App(s) you plan on developing (category and brief description)


At some point, we had to mention Twitter, right? We strongly encourage developers establish a connection with their local field evangelist, since they will be the ones ultimately putting phones into the hands of developers, but they can also point you in the right direction for solving problems, get you connected to other partners, and generally help out. To make it easier to get to know your local evangelist, we’ve set up this list – wp7dev/champs (

In Closing

This is a big milestone for everyone involved in Windows Phone 7 – inside and outside of Microsoft – and we hope you share in our excitement. With the Beta release of the tools, developers can build apps with a “ship it” mentality. There have already been so many amazing apps shown running on the emulator, and a lucky few who have been able to deploy to the phones at our developer events. We’re blown away by the early look at the apps, all of the sharing in the community, the blogging, and the screenshots. There’s a huge team of people here in Redmond who are all watching for new content tagged with “wp7dev” or “Windows Phone 7 Development.” It’s not uncommon for links to get passed around with a “wow, check out what these guys did!”  Keep it up, and keep the faith.
