I have installed all the tools for development with Xamarin in Visual Studio 2015, but somehow I do not see Blank App (Native) template when I create new project. I am only able
VS 2015 caches a lot and that usually means a lot of troubles.
Close Visual Studio 2015.
After restoring Xamarin, go to C:\Users\user_name\AppData\Local\Microsoft\VisualStudio\14.0\VTC and type on the search box cache.bin
NOTE - You will only see those files if you set the show hidden files option.
Delete all cache.bin files.
Reopen VS2015. All your Xamarin templates will be there and they show the appropriate icon.
Try this(from msdn):
In Control Panel, open Programs and Features, choose the Xamarin item, and click Change. In the setup wizard for Xamarin that appears, click Next and then Change. In the list of optional features to install, expand Xamarin for Visual Studio 2015, choose will be installed on local drive, and click Next to proceed with adding the feature.
Visual Studio updated Xamarin Blank App option to Mobile App (Xamarin.Forms). Once you have selected the Mobile App (Xamarin.Forms) option, you can create a Blank App as you like. I make an creating directions GIF.
