Why is SynchronizationContext.Current null in my Winforms application?

Question

I just wrote this code:

System.Threading.SynchronizationContext.Current.Post(
    state => DoUpdateInUIThread((Abc)state), 
    abc);

but System.Threading.SynchronizationContext.Current is null

Answer 1

See this explanation.

SynchronizationContext.Current is only set in the main thread (which is the only thread where you don't actually need it)

The blog post proposes a workaround.
