That's good news for WP coders who would want to port the 60, 000+ applications for the mobile OS to Windows 8's application store. With the upcoming Apollo version, the alleged Windows Phone 8, the porting process should be even easier, as it is said to share the same kernel with Win 8.
In fact, a recent job posting by Microsoft hinted that Redmond is striving for automated compatibility tests of apps written for Mango when Apollo arrives later in the year. "Automated testing of marketplace applications written for Mango, but running on Apollo. Write code, file bugs", reads the posting, debunking the rumors that were being spread that the apps will have compatibility issues.
