Answer 1

The WorkbookViewId property of the SheetView class is a required attribute/property. Try this:
SheetView sheetView = new SheetView();
sheetView.ShowGridLines = new BooleanValue(false);
sheetView.WorkbookViewId = 0;
sheetViews.Append(sheetView);
ws.Append(sheetViews);
That uses the 1st (default) workbook view. Don't worry, you don't have to explicitly create a WorkbookView child of the BookViews class, which is a child of Workbook. Unless you want to, of course. :)

I tried this way but it was failing but able to identify what is missing. By default when creating a spreadsheet from scratch, there is no default workbook view. So need to create new workbook view.
spreadSheet.WorkbookPart.Workbook = new Workbook(new BookViews(new WorkbookView()));
Then create sheet view.
worksheetPart.Worksheet = new Worksheet(new SheetViews(new SheetView(){WorkbookViewId=0,ShowGridLines=new BooleanValue(false)}), new SheetData());
NOTE: When create columns in the excel workbook, the elements should be created in a sequence. The sequence is
Sheet Views
Sheet View Formatting
Columns
Sheet Data
Enjoy Open XML SDK but Microsoft does not provide very powerfull documentation.
