title: gembox spreadsheet Calculate method not available
body: <p>GemBox Spreadsheet (<a href="https://www.gemboxsoftware.com/spreadsheet" rel="nofollow noreferrer">https://www.gemboxsoftware.com/spreadsheet</a>) documentation indicates a Calculate method is available at the excel file level object. However this Calculate method is missing when you reference the main library. Do I need a different library for this. There is nothing about it on their site.</p>
