DebuggerDisableUserUnhandledExceptionsAttribute
If a .NET Debugger is attached which supports the Debugger.BreakForUserUnhandledException(Exception) API,
            this attribute will prevent the debugger from breaking on user-unhandled exceptions when the
            exception is caught by a method with this attribute, unless BreakForUserUnhandledException is called.
            
                namespace System.Diagnostics
{
    [AttributeUsage(AttributeTargets.Method)]
    internal sealed class DebuggerDisableUserUnhandledExceptionsAttribute : Attribute
    {
    }
}
