Microsoft has released the second build to developers for the preview version of Visual Studio '15', which is the code name for the next major release of its software development tools. The new build adds a few new features along with bug fixes.
In a blog post, Microsoft stated:
This preview like the previous one, lays groundwork for the next version of Visual Studio. We primarily focused on bug fixes and a few feature updates. New features include; making the account settings dialog more accessible to screen readers, diagnostics improvements to help track down focus related issues, Edit and Continue for XAML apps, and simplified debug configuration in Folder view. Preview 2 also includes the latest Visual Studio Tools for Apache Cordova Update 9 which supports Cordova 6.1.1.
Microsoft will likely release more preview versions of Visual Studio "15" before it is officially launched
