lightswitch deployment in VS 2012

lightswitch deployment in VS 2012

I have created a lightswitch extension using VS 2012 say project name as
SampleLSExtension. Builded the created lightswitch project.
Then, instead of installing SampleLSExtension.vsix file i have shipped
SampleLSExtension.lspkg and extension.vsixmanifest file to the following
location.
*C:\Program Files (x86)\Microsoft Visual Studio
11.0\Common7\IDE\Extensions{Company Name}{Control Name}{Version}*. After
this i opened VS 2012 and checked, this extension is not configured VS
2012. I am not able to see my extension in Extension manager {Tools->
Extension manager and updates}.
While installing SampleLSExtension.vsix file it is configured in VS 2012.
Whether my way is correct or not? Could you please tell anyone, where i
did the mistake? Is any further settings needed for configuring this in VS
IDE?
