The Prepar3D SDK lets you program add-ons or contents for Prepar3D. The present version is directly compatible with Prepar3D v2 2, and is back-compatible with the previous versions of SimConnect.dll files. But the DLL provided with the SDK cannot be used to connect to FSX, ESP or any previous release of Prepar3D.
