problems with multiple CefSharp3 instances

[ray007]

I'm building an application with CefSharp3 that currently still resembles the Wpf-example quite a lot.
Starting it up once works fine, getting a second instance running gets me an error dialog shortly after starting: CefSharp.BrowserSubprocess has stopped working.
Trying to start CefSharp.Wpf.Example which me application is running gets the same result. Same with trying to start CefSharp.Wpf.Example twice in parallel ...

All this happening with VS 2010 and .NET4.

Any ideas? Should I try to go with CefSharp1 for now?

Try the latest code on master (not the latest NuGet package, it's a bit old by now). Does it still not work?

And no, please don't use CefSharp1 if you don't must. 😃

Yep, working from master things look better, thank you.

I didn't intend to use CefSharp1, but it seems I might miss CefSharp.Wpf.WebView:RegisterJsObject(...) and friends...

That's a nice confirmation to get in for the recent #212 related changes done by JanEggers!

You are right CefSharp3 isn't feature-wise a 1-to-1 with CefSharp1 yet, and if you really need #159 that is still a good reason to stay on version 1. But for now I guess focus is on making sure what is there is as stable as possible, then next as easy to consume as possible. I hope that is somewhat in line with what @perlun is thinking, and what people are generally here for - otherwise please enlighten me 😄

More related to the reported issue with CefSharp.BrowserSubprocess has stopped working though; I have actually also seen crashes and some times freezes. A place where it's easiest for me to provoke it is -- oddly enough -- to navigate to GitHub e.g. https://github.com/cefsharp/CefSharp/issues (from the bottom of the CefSharp.Wpf|Winforms.Example home page). I think it would be good if others could either confirm or reject seeing that behavior. It's entirely possible it's only a local issue here at me ...

I have kept a few WER reports, which I can share if they are of any use? What else would be of value to collect when a crash/freeze is seen?

[perlun]

Good to get it confirmed, closing. @jornh, I suggest you file a separate issue about that problem and enter the details there.

[ray007]

Too bad, CefSharp.Cef.RegisterJsObject() pretends to work but doesn't...

[perlun]

You're right. We should remove that method until it gets fixed, it's just confusing right now. (It's quite a bit of complexity getting it working, so that's why it's not there yet)
