I built a web page in VS 2012 that connects to a mongodb and returns records to a gridview. It works well. I am trying to recreate that page within SharePoint. I basically cut and pasted the code from the working page into the SharePoint site and then added the references to the mogodb drivers. The page compiles and builds without errors. When I go to run the page and click the search button to return the records from the mongodb, I get the error: Could not load the file or assembly 'MongoDB.Driver. . .' The system could not fins the file specified. Like I said, it works fine in the first web application, but not in SharePoint. I am completely new to SharePoint. Is there something I am missing with regards to references, or something else like that? Any ideas would be appreciated. It is SharePoint 2013, building the pages in VS 2012.
