CefSharp allows to be started in single-process mode when passing the command line argument --single-process. Is there a way to enable this from the application itself (programmatically, on startup, by default)?
I don't see it anywhere in CefSharp's code. The flag might be captured somewhere lower-level.
Single Process mode is not supported in CefSharp (It's not supported in CEF either) so we don't expose a way to programmatically set the relevant property.

There are many scenarios where things just crash. See http://magpcss.org/ceforum/viewtopic.php?f=14&t=13259&p=28501#p28501 for one such example.
Basically use at your own risk.
