Building

1. Copy CASModbusStack_Win32_Debug.dll, CASModbusStack_Win32_Release.dll, CASModbusStack_x64_Debug.dll, and CASModbusStack_x64_Release.dll from the CAS Modbus Stack project into the /bin/ folder.
2. Use Visual Studios 2019 to build the project. The solution can be found in the /ModbusRTUSlaveExampleCSharp/ folder.

Note: The project is automaticly build on every checkin using GitlabCI.
