Hi ..
I wrote a code in VB:NET to manipulate Excel files. The code works fine but when I debug it I can retrieve the value of variables only before the line Dim workbook = New XLWorkbook("excelfile")
after the execution of this line I can't check variables values..I receive this error:

error BC30652: Reference to assembly 'ClosedXML, Version=0.104.2.0, Culture=neutral, PublicKeyToken=null' containing type 'XLWorkbook' is required. Add one to the project.

These are the references in the project

Can you help me to understand where is the problem?
