Open n2ossareh opened this issue 1 year ago • 2 comments

Description

  1. in "for" statement for the view, there is an ! mark just before the second semicolon. Please remove it.
  2. The ViewData["Title"] is set to "Welcome", but it has not been used in the title-element. Instead the hardcoded string "Welcome" has been re-used. Please change the Title element to @ ViewData["Title"] .

Hello @n2ossareh ... The ! is present by design. It's a null-forgiving operator. https://learn.microsoft.com/dotnet/csharp/language-reference/operators/null-forgiving

I will briefly explain what the ! operator is doing there since this is a getting started tutorial and it is a relatively new feature.
