Validation Error (System.Xaml.Serialization) (UiPath.Excel.WorkbookApplication)

Hello guys, could someone help me with the following validation errors?

P.S the bot works perfectly only when I click the Validation Button these pops up and I would like to eliminate them in order to publish the Bot, I would really appreciate your help


Could you please try to import Microsoft.Office.Core to your project namespace

Please refer below link

@Rasoul Create Workbook variable in Excel Application Scope so it will be resolve

Perfect! the first validation issue is resolved, any ideas about the other one ?

Okay I was also able to find System.Xaml.Serialization from imports and it worked, even thu I tried finding it many times before, but apparently I had to find it manually not in the search bar !
