If you want to create a console app which access the object client model of SharePoint, for example to create lists, fill lists or get some date you should pay attention to some useful tipps.
- add the Microsoft.SharePoint.dll
- use .Net Framework 3.5
- make it as x64 bit application, otherwise it will not find the SPSite
I think that should help, especially the last point, which i always forget and when the error occurs, i remember it sooner or later 🙂
