after bump

(...)
  "buildSteps": [
    {
      "args": [
        "build",
        "Cmf.Connect.IoT.Driver.Oib.SetupCenter.sln"
      ],
      "command": "dotnet",
      "workingDirectory": "C:\\Work\\Packages\\Features\\IoT-OIB\\OIBExtensions\\SetupCenter\\Cmf.Connect.IoT.Driver.Oib.SetupCenter"
    },
    {
      "args": [
        "build",
        "Cmf.Connect.IoT.Driver.Oib.Traceability.sln"
      ],
      "command": "dotnet",
      "workingDirectory": "C:\\Work\\Packages\\Features\\IoT-OIB\\OIBExtensions\\Traceability\\Cmf.Connect.IoT.Driver.Oib.Traceability"
    }
  ]

if we look to the workingDirectory, we can see the value changed
