Microsoft has given its Windows Phone Developer Training Kit a Beta refresh.
The company says its part of its efforts to help developers jumpstart their development of Windows Phone applications.
Microsoft has added two new labs:
Using Windows Phone Launcher and Choosers In Your Applications
Understanding the Windows Phone Application Lifecycle (handling Tombstone)
“A new functionality in this Beta release tool is the exposure of APIs for using Windows Choosers and Launchers,” Microsoft says on its Windows Phone Developer Blog.
“The launchers and choosers framework enables Windows Phone applications to provide a set of common tasks for users, such as placing phone calls, sending email, and taking pictures.”
“As you probably already know, Windows Phone allows only one application to run at any given time in the foreground, and no 3rd party applications are allowed to run in the background. Therefore when a user navigates away from your application, either to a chooser like picture chooser, or to a launcher like phone call, Windows Phone operating system terminates your application,” the company said.
