The .NET server stack has been fully updated and tested. The gpstracker.bak file is the database backup file created with sql server 2012.

Please note that this is an asp.net website, not a web application. Its means you need to put source files directly onto an asp.net web server like IIS and it will be compiled on the fly. To open this project in visual studio for web (2012), you need to go to the file menu and open website, then select you iis web server and open the gpstracker website that you created there.
