Hi all, I have a WCF service hosted in IIS on my laptop which works perfectly, I recently installed Windows 2012 Server on my server and thought I would install my WCF service on it, I copied all the files from my service to the server , installed it on IIS the usual way and tried to run it but I receive this error

Could not load file or assembly 'System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral - followed by lots of key details

My application doesn't even use razor nor is there a direct reference to it anywhere that I can see - any ideas ?
