Get last cell address in Excel worksheet

I've noticed over the years developers asking how to get the last used cell in an Excel WorkSheet via Excel automation. So I created a GitHub repo which demonstrates using Excel automation how to get the last used cell address along with using SpreadSheetLight library.

When downloaded you will need to check the projects ExcelUsedColumnsLib and ExcelUsedColumnsLib_vb references to see if the reference for Microsoft.Office.Interop.Excel is valid as you may have a different version of Excel. For SpreadSheetLight right click on the Solution, select restored packages.
