Yeah. The place from whereby I"m calling that function is the location where I receive my data. The reasonable I"m trying to implement is whenever the data gets updated, the UI demands to be invalidated as well. Ns think that error blog post is getting here because I"m do the efforts to access the UI thread from the key thread yet I don"t know exactly how to get over it. Apparantly, the
technique didn"t seem to work. What ways deserve to we invalidate the UI with a thread exterior the UI thread?

Noesis objects created in one thread can not be accessed from a different thread. We don"t carry out a mechanism to settle that, you must do it yourself, depending on the communication you space using.If Dispatcher is not available in Unity, what the recommended system then?

I additionally ran in several of these issues when update the ViewModel from exterior the calculation thread.Here is my fix, although ns think there need to be a better way.Note that i"m not making use of Unity, but Dispatcher is not available in the Noesis application framework.I usage the below patern: conserve to list -> OnRender() -> Execute every little thing in the list.

I also tried the usual _synchronizationContext.Send/Post way, however i gained the very same errors, or that didn"t upgrade at all.
