Hanging when calling via CefSharp about revit.async HOT 6 CLOSED

Update: It seems that this occurs when the UI in CefSharp is continuously updated while the callback is being executed (loading animation). The weird thing is, the freezing only occurs when the addin is run without a visual studio debugger attached...

from revit.async.

Calling Wait() is not wise in UI thread, generally you can push result back when an asynchromous task finishes. If there isn't a way to do that, just do some polling to get the result periodically.
I did some research and it seems CEFSharp has supported returning Task from .NET, see cefsharp/CefSharp#2758
You can also use a callback to resolve this issue

from revit.async.

Unfortunately, Revit doesn't support the newest version of CefSharp that natively supports async :(

I suppose polling would work, thanks for the suggestion!

What exactly do you mean by using a callback to resolve it?

If you pass a js function down to .NET, you will get an IJavascriptCallback object by which you can pass data back. In your javascript code, you can do some wrapping using Promise to use async fashion

Thanks. I tried the polling method which surprisingly didn't work either.

But, an interesting turn of events.. I switched from using CefSharp with WPF to CefSharp with WinForms and everything is working again. Notably, the web page performance is much better. I think the WPF off-screen rendering technique is just so resource hungry it wasn't letting anything else get scheduled...

Looks like this is more of a CefSharp issue than Revit.Async so will close. Thanks for sharing your thoughts!
