New Post: Exception when creating or loading workbook: When using relative paths, make sure the current directory is correct.

I'm getting an exception with only a single line of code;

    static void Main(string[] args)
    {
        XLWorkbook workbook = new XLWorkbook(); 
    }

"The type initializer for 'ClosedXML.Excel.XLWorkbook' threw an exception."
"InnerException: When using relative paths, make sure the current directory is correct."

This must be a configuration error? I've added "ClosedXML" and "DocumentFormat.OpenXml" to References. I also get this exception trying to load a workbook.

It has been a frustrating day of Koogra, NPOI, OpenXML! They all seem to have their quirks. All I really want to do is dump the cell contents of every named range in a workbook. With OpenXML I couldn't get it to write dates properly and cycling through each cell in the range was quirky. I've tried multiple StackOverlfow examples.

I Googled the exact text of the exception & it doesn't appear anywhere.

Thanks in advance for any ideas.
