en-UK is an invalid culture identifier - VB.NET/C#/Csharp

We are used to en-UK as culture. but for some reasons MS doesn't support en-UK (UK is used for Ukraine)

Hence replace

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-UK", false);
            

with

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB", false);
