MDT contains tools for importing and exporting configurations of runtimes and sessions (Sessions, Session Links and Command Line Sessions). This mechanism allows for sharing the aforementioned configurations between developers and ensures that whole developer team is working with the same sessions and runtimes settings.
Runtimes can be exported from MDT using Export Runtimes Wizard and imported back to MDT using Import Runtimes Wizard.
All kinds of sessions can be exported from MDT using Export Sessions Wizard and imported back to MDT using Import Sessions Wizard.
