Parameter 'constraint' is unread.

'AsyncVoidCodeFix' registers one or more code fixes, but does not override the method 'CodeFixProvider.GetFixAllProvider'. Override this method and provide a non-null FixAllProvider for FixAll support, potentially 'WellKnownFixAllProviders.BatchFixer', or 'null' to explicitly disable FixAll support.
