TimeZoneInfo in WinApi return bad value

Question

It seems that I found a mistake in WinApi. When I use TimeZoneInfo.Local.DisplayName in Debug in my Visual Studio 2015 it return right variant to me, as example "(UTC+02:00) Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius". In release mode(.net native) same api return me "FLE Standard Time". Be greatfull to hear how to get time zone information in other way, or how to fix this issue.

You most likely have missed something in your code. One mistake that I made before, and is easy to make is confusing DisplayName with DaylightName:

        static void Main(string[] args)
        {
            var timeZoneName = TimeZoneInfo.Local.DaylightName; //FLE Standard Time
            var displayName = TimeZoneInfo.Local.DisplayName; //(UTC+02:00) Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius
        }

For reference, you can check Time Zone IDs
