In this post, we will discuss how to resolve the issue which comes when we try to run a windows application in SharePoint 2016. Recently I was doing a demo in windows application (Server Object Model / Microsoft.SharePoint.dll) in visual studio 2015.


When I run the application it gives me an error as:

System.PlatformNotSupportedException occurred in Microsoft.SharePoint.dll.

An unhandled exception of type ‘System.PlatformNotSupportedException’ occurred in Microsoft.SharePoint.dll

Additional information: Microsoft SharePoint is not supported in the 32-bit process. Please verify that you are running in a 64-bit executable.
