Unable to deploy visual web part in SharePoint

I am trying to create a Visual Web Part in Visual Studio 2012 for SharePoint 2010.

It builds fine but while deploying gives error : "Error occurred in deployment step 'Add Solution': Operation is not valid due to the current state of the object".
 
(This happens also with a blank sharepoint project)

Any suggestions?

The first two suggestions I tried earlier but did not work.

Hi Niya,

Please try the following steps:
1. Project >> Properties >> Application >> Target Framework
set it to 'Framework 3.5'
2. Project >> Properties >> Build >> Platform Target
try 'Any CPU'

Do let us know if you need more help..
Enjoy!!.
