I'm doing the following
var stream = File.Open(path, FileMode.Open, FileAccess.Read);
IExcelDataReader reader = ExcelReaderFactory.CreateOpenXmlReader(stream);
however, i get the error on the second line saying
"Severity Code Description Project File Line Suppression State Error CS0266 Cannot implicitly convert type 'Excel.IExcelDataReader' to 'Assignment9.Controllers.IExcelDataReader'. An explicit conversion exists (are you missing a cast?)"
I have added install-package exceldatareader, etc.
