Main.xaml language 'VisualBasic' is incompatible with project's language 'CSharp'. This configuration is not supported

Try this possible solution:

  1. Open the .xaml in Studio (double click on the .xaml file).

  2. Close the UiPath Studio application.

  3. Open the generated project.json file and look for

"expressionLanguage": "CSharp"

and replace it with

"expressionLanguage": "VisualBasic"
  1. Save the project.json file and close it.

  2. Reopen the .xaml file in UiPath Studio.

Let us know if you still have the error after performing the above.
