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.
