Earlier today in the MIX10 keynote, Scott Guthrie announced the availability of the Windows Phone Developer Tools CTP.  This CTP is available for download starting today, and the setup package will download and install the following:

• A CTP of the new Visual Studio 2010 Express for Windows Phone
• Tools and framework to develop Windows Phone applications and games with Silverlight
• A CTP of XNA Game Studio 4.0 that allows you to develop Windows Phone games with the XNA Framework
• A Windows Phone 7 Series emulator that can be used to deploy and debug Windows Phone applications and games
• Add-on to allow you to use the Visual Studio 2010 Ultimate Release Candidate to develop Windows Phone applications and games if you have it installed

XNA Game Studio-specific information

For XNA Game Studio developers, it is important to note that there is not a standalone installer for the XNA Game Studio 4.0 CTP like you have been used to from past releases.  Instead, you will need to download and install the Windows Phone Developer Tools CTP, and that will install the XNA Game Studio 4.0 CTP for you behind the scenes.

Here are some links to information that is specific to the XNA Game Studio 4.0 CTP:

• Introductory information about XNA Game Studio 4.0 - http://blogs.msdn.com/astebner/archive/2010/03/09/9975843.aspx
• XNA Game Studio 4.0 CTP news item - http://creators.xna.com/news/mix2010
• XNA Game Studio 4.0 CTP release notes - http://go.microsoft.com/fwlink/?LinkId=185269 (this is the same set of release notes as for Windows Phone Developer Tools, the XNA Game Studio 4.0 information is towards the bottom)
• XNA Game Studio 4.0 CTP documentation - http://msdn.microsoft.com/en-us/library/bb203894(XNAGameStudio.40).aspx
• XNA Game Studio forums - http://forums.xna.com/forums

One important note - the XNA Game Studio 4.0 CTP includes project templates for Xbox 360 games in addition to Windows and Windows Phone games.  However, you cannot deploy, run or debug Xbox 360 games created with this CTP.

If you encounter Windows Phone Developer Tools CTP setup failures

If you run into an installation or uninstallation failure for the Windows Phone Developer Tools CTP, you can use the log collection tool to gather your setup log files.

For this CTP, this tool does not gather XNA Game Studio 4.0 setup log files, so if your setup failure is caused by the XNA Game Studio 4.0 component, you’ll need to gather those logs separately by zipping up all of the logs in the folder named %temp%\XNA Game Studio 4.0 Setup\Logs.

Once you have gathered your setup log files, you can upload them to a file server of your choice (such as http://skydrive.live.com), and post a link to the log files in the forums to get additional support.

If you run into uninstallation issues, you can use the cleanup tool described at http://blogs.msdn.com/astebner/pages/9544320.aspx to remove XNA Game Studio or the Windows Phone Developer Tools.
