In Visual Studio 2013, editing XAML files has suggestions from intellisense, as shown in the image below. While not perfect, they usually worked.
But I don't seem to have the same functionality in VS 2015 (despite Xamarin being installed here and the project building perfectly fine). Not only is there no Xamarin-specific intellisense (just generic XML intellisense), but VS issues messages (which it flags as errors) like:
The type 'ContentPage' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
Which also didn't happen in VS 2013.
Is VS 2015 officially supported? The installer seemed to imply it was and this is the only regression I've seen so far. This is on the RC version (14.0.22823.1) and with Xamarin for Visual Studio 3.11.666. This seems to be the most recent version.
