we would recommnend to clear analysisng steps:
- remove the references to all unneeded packages and cleanup imports i needed
- setup assembly entries in the XAML when needed
Do your modelling / implementation
When an issue occurs then check and make a separation:
- is it about the infrastructure (e.g. method not found)
OR - is it working, but the result is different from expected output.
For further discussions also let us know what is in use:
- targetframework
- UiPath Studio Version
- UiPath.System.Activites version
