If you have a Kartris install, then you can connect to this with VS 2013 without any errors:

The key is that you must have setup Kartris so that it is connected to a properly populated database. Kartris uses a custom resource provider to pull language specific text from the database rather than a resx file - this means all language specific text elements can be changed easily from the back end.
