I have a Universal Windows Platform project created in Visual Studio 2015. which uses C# as backend language, and XAML obviously as the front-end UI framework language all within .NET framework 4.6 version.
At random times when coding or editing the project, the XAML autocomplete doesn't work anymore, (not showing any UI controls, Converters, Styles...etc) and only shows these weird basic XML item suggestions:
!--, [!CDATA[ and ?
What is causing this behavior? and how can be fixed without restarting Visual Studio?
