Error: The type or namespace name ‘SharePoint’ does not exist in the namespace ‘Microsoft’(are you missing reference?)

Issue: I’ve got the above error when trying to run a simple code in the console application. Though added the Microsoft.SharePoint .dll from the following path C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.SharePoint.dll, was getting the error during debugging.

Resolution: Right click the Solution Explorer and click properties, In Application tab, .Net Frameworkf 4.0 Client Profile was selected by default, change it to .Net Framework 3.5 and debug again. Also change the Platform target in the Build tab to x64.
