cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?)

Error : cannot implicitly convert type \'bool?\' to \'bool\'. An explicit conversion exists (are you missing a cast?)

Answer 1

I'm facing your question when I'm using the null check operator ?.:

if (!RolesList?.Any()) //Not accepted: cannot convert bool? to bool

So I'm using this instead

if (RolesList?.Any() != true)
  //value is null or false

In your case you should set it like so:

obj.IsVisible = chkDisplayStuff.IsChecked ?? false;
