Question

Can anyone know what happening if we create two appdomains with the same friendly name?

    static void Main(string[] args)
    {
        var myDomain = AppDomain.CreateDomain("mydomain");
        var myDomain2 = AppDomain.CreateDomain("mydomain");
    }

As i noticed this is not throwing an exception, maybe the two local variable points to the same appdomain?

The friendlyName parameter is intended to identify the domain in a
manner that is meaningful to humans. This string should be suitable
for display in user interfaces.

As you can guess it could only get the user confused if you use the Friendly name in a UI
