I guess may be you are deploying your application when you install VS2008 on your development machine, .NET Framework 3.5 is installed as well. Also, when you create new web sites, by default the target framework is 3.5, and thus requires 3.5 assemblies to be present on the deployment environment.
Try this, Check in the control panel > add and remove programs > add/remove windows components > IIS, and under the installed options and make sure that your asp.net is enable under IIS. Make sure .net framework 3.5 is installed on your server. Further have you copied the bin folder on the server containing the reference to System.core?
