MediaTypeFormatter in the request CultureInfo

[dougbu]

Thank you for contacting us. To evaluate whether this is indeed an issue in ASP.NET Web API, could you please elaborate on the scenario and provide us with a minimal repro project that illustrates the problem, preferably hosted in a GitHub repo?

Details

Yes, in ASP.NET Core, async transitions should consistently carry the CultureInfo along.

In ASP.NET (non-Core), you may need to

• Move to a later version of the .NET Framework. .NET 4.6 introduced some SynchronizationContext improvements. What framework version were you using when you saw issues?
• Use the SynchronizationContext stored in HttpRequestMessage.Properties, assuming it's recent enough to include CultureInfo.
• Examine / fix any ConfigureAwaiter(...) calls in the application. ConfigureAwaiter(...) can change how information is carried as virtual threads are scheduled.

The other possibility is one of your dependencies has introduced a SynchronizationContext that does not carry CultureInfo.
