I assume that you are using VS2015 on an operating system prior to Windows 10. According to a post on Microsoft Connect, this behaviour is by design. When you're using VS2015 on Windows 8.1, there is no support for design view, you have to upgrade to Windows 10 instead:

"If you are developing Windows 10 applications, this is by design since the designer requires Windows 10 in-order to show the design surface for UWP applications since we run application code. In Windows 8.1 and Windows 7, you will only get intelliSense. If you want full support for the design tools, you need to develop the application on Windows 10."
