Please fork https://github.com/cefsharp/CefSharp.MinimalExample and provide an example that reproduces your problem. |
Just to be clear this is not officially tested/supported. |

OK！CefSharp.MinimalExample settings.CefCommandLineArgs.Add("renderer-process-limit", "1");BrowserForm.cs add code in BrowserForm constructor: browser.JavascriptObjectRepository.ResolveObject += (sender,e)=> {
var repo = e.ObjectRepository;
if (e.ObjectName == "boundAsync2") {
BindingOptions bindingOptions = BindingOptions.DefaultBinder;
bindingOptions.CamelCaseJavascriptNames = false;
repo.Register(e.ObjectName, new BoundAsync2(), isAsync: true, options: bindingOptions);
}
};Add Bound Class: public class BoundAsync2 {
public string hello(string s) {
return "hello " + s;
}
}test.html: <html>
<body>
<img src="1.png?a=120309093"></img>

<script type="text/javascript">
function Main() {
var foo = async function () {
var ret=CefSharp.RemoveObjectFromCache("boundAsync2")
alert("1“)
var ret2=CefSharp.DeleteBoundObject("boundAsync2")

try{
await CefSharp.BindObjectAsync({ NotifyIfAlreadyBound: true, IgnoreCache: true },"boundAsync2")

alert(err);

alert("3")
var ret3=await boundAsync2.hello(" world")
alert(ret3)
};
foo();
}
$(function () {
Main();
});
</script>
</body>
</html>Put test2.html in 192.168.1.100，and put test.html in c:\ 1.access 192.168.1.100\test2.html ,and it will alert "1"，”2“， “3” and “hello world”
