In VSTA when we want interact with SharePoint objects, then we got this below error.
“The Web application at could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.”
The reason is that when we install Office 2010 32 bit and now targeting the 64 bit environment. So, just uninstall the Office 32 bit and install 64 bit version. It will resolve the issue.
