This error is very misleading. I spent many precious hours trying to fix it. If you are certain that your Visual Studio is up to date, you do not need to update nor repair the Visual Studio 2015.

Please follow the next steps:

1. Click Ok on the Error message.

2. Go to your solution explorer and right click on your projects with the (update required) tag.

3. Right click the Project and select the option: "Edit MyProject.csproj"

4. Edit all the appearances to the Windows 10 SDK to a lower version like 10.0.10240.0

From this:

  Windows Desktop Extensions for the UWP


  Windows Mobile Extensions for the UWP


UAP
10.0.10586.0
10.0.10240.0

To something like this:

  Windows Desktop Extensions for the UWP


  Windows Mobile Extensions for the UWP


UAP
10.0.10240.0
10.0.10240.0

Repeat for all the projects in your solution, and reload the projects multiple times (VS has a problema to refresh its structure), you have to be patient and probably restart it a couple of times.

And you are good to go! For more info please review this page: https://msdn.microsoft.com/en-us/library/Mt148501.aspx#RCUpdate10CSharp
