The Gemalto IDPrime MD 3811 is a Dual Interface Javacard with MIFARE Classic 4K & DESFire EV1 4K emulation. "MD" stands for Minidriver, which means that a mini driver is loaded for this card via Windows Update and can then be used via the Microsoft Base Smart Card Cryptographic Service Provider (MS Base SC CSP).
The Gemalto IDPrime MD 3811 is therefore to be used in the same way as the Gemalto .NET Cards used to be.
