> System.FormatException: Failed to convert parameter value from a String to a DateTime. : An error occurred while updating the entries. I assume it has to be something relatively simple and hope that someone can shed some light on this. I can't save my record because of this error. I attempted to find documentation for the datetime format that EF Core is expecting with no success. Gl.LastUpdate =DateTime.ParseExact(stringDate,format,CultureInfo.InvariantCulture) Дb.SaveChanges() //Entity Framework Core Below is a link to the latest attempt in Visual Studio with some watches set for pertinent values.

I have looked at almost a hundred posts regarding something similar to no avail. There is an unknown word starting at index 0. It keeps failing with the following error:ДЇormatException: The string was not recognized as a valid DateTime. I have spent 4 days trying to get EF Core to save a datetime value for a record.
