I am stuck in creating an universal project under windows 10 using visual studio 2015 
.
I have tried everything from OS Reinstall to Windows Developer tools stand alone installer but had no luck.
The error I am getting is
One or more projects require framework sdk .netcore , version = 5.0.
I have even installed KB3073097.exe which contains .netcore, version = 5.0
i have managed to simulate the problem you are experiencing by deleting the file FrameworkList.xml in the following path:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v5.0\RedistList
After i deleted the FrameworkList.xml file i've got the same Error message you are receiving.
please check if you got that file in the path mentioned above.
also here is the contents of the file(if you want to create it manually)
<?xml version="1.0" encoding="utf-8"?>
<FileList Redist="Microsoft-Windows-CLRCoreComp.5.0" Name=".NET for Windows Universal" RuntimeVersion="5.0" ToolsVersion="4.0">
</FileList>
another option if you dont want to create it manually is by installing the windows 10 sdk
Somebody seemingly found a solution: https://social.msdn.microsoft.com/Forums/vstudio/en-US/f868b586-cffe-46d6-a453-95b014bce9ae/uap-project-not-creating?forum=visualstudiogeneral
How about this? I think somebody seemingly found a solution at :
