I had the same problem in Visual Studio 2015 Update 3, Windows 10 Build 10586.494.

The error came up when trying to start any UWP app that I compiled without .NET Native Toolchain. With Native Toolchain enabled, the apps would start.

Installing a new (blank) app manually fixed the error for me:

• Start VS 2015
• File > New > Project.
• Blank App (Universal Windows) Visual C#. OK.
• Make sure to be in Debug config
• Right click on Project > Store > Create App Packages
• No. Next.
• Select Debug for all architectures.
• Create
• When packaging is finished, open Explorer to the project path / AppPackages / [...]_Debug_Test
• Right-click on Add-AppDevPackage.ps1 > Run with PowerShell
• Follow the instructions
• Start the installed app from Start Menu
