Include Manifest in Vs 2012 window 8

I tried to simulate Alt + tab in Vs2012 express and have Window 8, it did not simulate but the same code work fine on window 7 and simulate Alt+tab as well,
after goggling I found that, to stop from the malicious code Window 8 requires special access level that is high privilege level so I included Manifest file in my project

<requestedExecutionLevel level="highestAvailable" uiAccess="true" />

I get following error in messagebox when tried to run the application for vs 2012

The application manifest has the uiAccess attribute set to 'true' running an accessibilty application requres following steps described in help.
and then I left with two button on same message box OK and Help, but when I clicked Help button on message Box, I redirected to page http://msdn.microsoft.com/query/dev11.query?appId=Dev11IDEF1&l=EN-US&k=k(vs.debug.error.launch_elevation_requirements);k(TargetFrameworkMoniker-.NETFramework,Version%3Dv4.0)&rd=true[^],
but I do not see any solution for my problem on that page.

Thank You
