Incompactible error in Visual Studio 2012 for SharePoint 2013 projects

I came across this error after installing VS 2012 and when I was trying to open SharePoint 2013 projects.

All my projects were not loading and showed incompatible error

This article proposes solution to one of many reasons for this error 

Solution :

VS 2012 when installed does not install project templates for SharePoint 2013.

So if to go to File- > New->Project->Office Apps-> you can only see SharePoint 2010 templates

so now you need to install templates for SharePoint 2013, by default SharePoint 2013 templates do not get installed and they have to be installed seperately

You can find file to download on this url :

Download each project on by one and install all mentioned in the link

Once you install this, all your projects would open,work and get deployed as required
Cheers !

I had to write this blog because none of the available blogs have addressed this simple solution and because I wasted my 2 working days trying to figure out the issue

Even if this does not work :

• Donwload and install SDK patch
• Download and install KB2781514 for Visual Studio

Hope this helps
