Hi,

I think I'm running into the same issue, but in my own app — after upgrading it from 2019.1 to 2020.1, I get this message on startup. `System.Threading.Thread.CurrentThread.GetApartmentState()` returns STA.

Will there be a service release soon?

Thanks!

Hi,

the latest service  release in the download section is still 20.1.42. 

Why is 20.1.47 not listed in the download section? Is it a beta? Is 20.1.47 relieable?

Hello Mike + Divya,

Thank you both for the quick responses. The reflection-based workaround ended up not being necessary as SR 47 does indeed fix it. :)

Thanks again,

Sören Kuklau

Hi Sören,

The issue has been fixed internally and it's fixed in the latest bi-weekly build which is available for download. I will see about getting you a link or some instructions on how to download it. :) 

If you would prefer, you can work around the issue...
Copy this method into your code and then call it for each DockManager component in your application. You only need to call this method once, perhaps in your form's constructor. It requires full trust, though, since it uses reflection. 

private void SuspendSTAThreadWarning(Infragistics.Win.UltraWinDock.UltraDockManager dockManager)
{
var dockManagerType = dockManager.GetType();
var STAThreadWarningSuspendedProperty = dockManagerType.GetField("STAThreadWarningSuspended", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
STAThreadWarningSuspendedProperty.SetValue(dockManager, true);
}
