Hi, I am trying to implment a splash screen in the easiest way possible(at the minute) using the splash screen build option. However I keep getting the error:

"The calling thread must be STA, because many UI components require this"

I have absolutly no idea what this means! If someone could enlighten me it would be appreciated.

Thanks

Solution 1

It means that the threading model of the app is incompatible with the component you're using. The easiest fix is to create your own form to show the splash, or write a Win32 app that shows it and launches your main app. We do the latter, b/c WPF is slow to start and the splash took a while to appear, otherwise.

Solution 2

If the splash screen is called from the main thread you need to mark it as STAThread.
Read more about STA here[^].
