Exception thrown: 'System.NotSupportedException' in WindowsFirewallHelper.dll

[ctechid]

I get a warning like this in the immediate window when FirewallManager.Instance.Rules.SingleOrDefault is executed.

I use VS2022 with C# Desktop with Framework 7.0. The program works fine but a warning appears like that. Can it be ignored?

Thanks.

Do you have break on exception active?
