Projects

• OBD.NET.Common - NetStandard 1.4 Library for platform independent stuff
• OBD.NET.Desktop - Implemenation of SerialConnection on full .NET Framework
• OBD.NET.Universal - Implementation of BluetoothSerialConnection for connecting to Bluetooth Adapter on UWP
• OBD.NET.ConsoleClient - Example client application using SerialConnection on full .NET Framework

Usage

• Add OBD.NET.Common and OBD.NET.Desktop packages to project
