I get the following error when trying to build (Debug > Windows Phone > Device) the default Cordova TypeScript project :
No Windows Phone 8 emulators installed. Please install Visual Studio 2013 with Windows Phone 8 tools selected to install the emulators
Note: I was using the release candiate of Visual Studio 2015 and just installed the trial version of Visual Studio Community 2015.
Installing Visual Studio 2013 Windows Phone 8 tools can't be the correct solution.
Thanks for upgrading to the RTM VS 2015. Unfortunately, you do require VS2013 for Windows 8 emulators to be installed. They aren't available on VS 2015 or there is no stand-alone installer for the emulators. But you should be able to deploy your Windows 8 application on Windows 8.1 emulators, if that helps.
