Async Thread.CurrentThread.CurrentCulture in .net-4.6
Due to the following information from Microsoft, I have updated my code a bit. Looks like they updated the current culture to something I could use.
For applications targeting the .NET Framework 4.6 and later, CultureInfo.CurrentCulture and CultureInfo.CurrentUICulture are stored in the ExecutionContext thread, which flows through asynchronous operations. (source: https://msdn.microsoft.com/en-us/library/dn833123(v=vs.110).aspx )
using System;
using System.Globalization;
using System.Threading;
using System.Threading.Tasks;
class Program
{
static void Main(string[] args)
{
Console.WriteLine("start " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
RunAsync().Wait();
Console.WriteLine("Finish " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
Console.ReadKey();
}
static async Task RunAsync()
{
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("de-DE");
Console.WriteLine("1 " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
string cultureInTask = string.Empty;
await Task.Run(() => cultureInTask = Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId).ConfigureAwait(true);
Console.WriteLine("2 " + cultureInTask);
string twoA = await TestMethodAsync();
Console.WriteLine("2a " + twoA + " " + Thread.CurrentThread.ManagedThreadId);
Console.WriteLine("3 " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
}
public static async Task<string> TestMethodAsync()
{
Console.WriteLine("2s " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
return await Task.Run(() =>
{
return System.Threading.Thread.CurrentThread.CurrentUICulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId;
});
}
}
Output:
start en-US 1
1 de-DE 1
2 de-DE 3
2s de-DE 3
2a en-US 4 4
3 de-DE 4
Finish en-US 1
But why is 2a returning to the US and not de-DE? Is it because executeContext is different? If so, how can I stay in the same execution context?

CurrentCulture
and CurrentUICulture
are independent properties. You install CurrentCulture
and you report that everywhere except 2a, which reports CurrentUICulture
. If you use the same property consistently throughout your code (or the property should be fine), it will give you the results you expect.
