Windows requirements

Device family	Windows IoT Extension SDK (introduced in 10.0.10586.0) Windows 10 Anniversary Edition (introduced in 10.0.14393.0)
API contract	Windows.Devices.DevicesLowLevelContract (introduced in v2.0)

Fields

Exclusive

Connects to the I² C bus address exclusively, so that no other connection to the I² C bus address can be made while you remain connected. This mode is the default mode.

Shared

Connects to the I² C bus address in shared mode, so that other connections to the I² C bus address can be made while you remain connected.

You can perform all operations on shared connections, but use such connections with care. When multiple client apps change the global state of the I² C device, race conditions can result.

An example use case for using a shared connection is a sensor that obtains readings without changing the state of the device.
