Sorry for replying late. I have tried as your repro steps in sample application of WPF, and it runs normally.
Could you provide more information about how to reproduce your issue?
Thanks.

1 year ago Got a similar issue here!
But the difference is when I am running my WPF or Winform application with VS 2022, my application will crash without any errors!
Here are my steps:
Create a HostApi class
[ClassInterface(ClassInterfaceType.AutoDual)]
[ComVisible(true)]
public class HostApi
{
public string SelectFolder()
{
string folderPath = null;
using (FolderBrowserDialog openFolderDialog = new FolderBrowserDialog())
{
if (openFolderDialog.ShowDialog() == DialogResult.OK)
{
folderPath = openFolderDialog.SelectedPath;
}
}
return folderPath;
}
}AddHostObjectToScript method to inject the HostApi instance to js
public MainWindow()
{
MyWebView2.CoreWebView2InitializationCompleted += MyWebView2_CoreWebView2InitializationCompleted;
}private void MyWebView2_CoreWebView2InitializationCompleted(object sender, Microsoft.Web.WebView2.Core.CoreWebView2InitializationCompletedEventArgs e) { _hostApi = new HostApi(); MyWebView2.CoreWebView2.AddHostObjectToScript("hostApi", _hostApi); }
3. Load this html with the `MyWebView2` browser
```html
<html>
<script>
function selectFolder() {
var result = window.chrome.webview.hostObjects.sync.hostApi.SelectFolder();
console.log(result);
}
</script>
<body>
<div style="margin-top:15px">
<button type="button" onclick="selectFolder()">test</button>
</div>
</body>
</html>test button, it will pop up the folder dialog, then wait about 1 minute, and the application will crash without any exceptions.

1 year ago I use MessageBox also crashes, after the dialog is opened and not closed wait a few seconds will crash, prompt return value 2147483651 (0x80000003).
My code is simple:
chrome.webview.hostObjects.dialog.Error(message, title);public void Error(string message, string title)
{
MessageBox.Show(message, title, MessageBoxButton.OK, MessageBoxImage.Error);
}Hi @getandplay @Crauzer @robincodex,
Could you provide more information about the exception? It seems that the issue arises when you use dialog in host object?

1 year ago I'm also getting this issue. I'm using WinForms with WebView2, and triggering a FolderBrowserDialog from a HostObject as well.
If I leave the FolderBrowserDialog open for longer then 20 seconds or so, it crashes my app. There is no exception. I also tried to add breakpoints in:
AppDomain.CurrentDomain.FirstChanceException +=...
AppDomain.CurrentDomain.UnhandledException += ...To get more details but the app crashes without hitting these events.
Not sure what's happening...

Running a message loop synchronously in an event handler in Webview can cause reentrancy issue. Please refer to https://docs.microsoft.com/en-us/microsoft-edge/webview2/concepts/threading-model#re-entrancy for more information about threading model in WebView2 and how to enable native code debugging for this scenario.

EmbeddedBrowserWebView!base::debug::BreakDebuggerAsyncSafe+0xd:
00007ffd`8c0e193d cc int 3So I expect this message to relate to using the hostObject.sync (or default sync) to trigger a function, and then hitting a message loop on that sync call somehow. However I'm not using sync, so I'm not sure why this is triggering here.
I've tried the following:
Please let me know if I can provide any additional details or troubleshooting...
[EDIT]:
Slightly cleaner workaround for now: have the host object function trigger Task.Delay(0).ContinueWith(_ => frmMain.Invoke(anotherFunctionThatTriggersFolderBrowserDialog))

1 year ago Could you provide more information about the exception?
It just crashed, I didn't get any exceptions. Even if I call DispatcherUnhandledException += App_DispatcherUnhandledException; . And I also check the windows application logs, can't find anything related there.
Do you have any idea to catch the exception?
It seems that the issue arises when you use dialog in host object?
Yes, and it has to use VS2022 to start the application. If run the application by double click the EXE file, it works fine.
BTW, I am using VS 2022 Preview in Mac Parallels.

1 year ago I found that: This is due to running a message loop (modal dialog) from WebView2 event handler, which is not recommended, as no further webview events will be process before the dialog is dismissed and returned from the event handler. If you show the dialog asynchronous outside of WebView2 event handler, then it will be fine. This is actually not a real crash. If you run the app without a debugger attached, it will not crash. If you run the app under a debugger, we will display a message in debugger with link to https://docs.microsoft.com/en-us/microsoft-edge/webview2/concepts/threading-model#re-entrancy, and break into debugger. That page has information on how to refactor the code to avoid this.

Good luck!

1 year ago Hi all,
It seems that this is a known issue. Hope this #2668 could help.

1 year ago Hi guys, I reread the documentation today and saw this code, which can solve this problem. I have tried it and the program no longer crashes.
https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/threading-model
private void CoreWebView2_WebMessageReceived(object sender, CoreWebView2WebMessageReceivedEventArgs e)
{
string msg = e.TryGetWebMessageAsString();
if (msg == "Open Dialog")
{
// Show a modal dialog after the current event handler is completed, to avoid potential reentrancy caused by running a nested message loop in the WebView2 event handler.
System.Threading.SynchronizationContext.Current.Post((_) => {
Form1 form = new Form1();
form.ShowDialog();
form.Closed();
}, null);
}
}

3 months ago Try this. This seems to solve the issue.
public async Task<string> OpenFile()
{
//Make the method async
//Add this line to make the method async
await Task.Yield();
var dialog = new OpenFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
return dialog.FileName;
}
return "";
}

1 month ago Im trying to move from CefSharp to WebView2 in a WinForms Application so I wanna move my code touching as less as posible the javascript code in the front-end. In my case, I need to return the result of the form (opendialog, savedialog) in the same call in a synchronously way, so that, the solution proposed by @robincodex doesn't work in my situation because I cant wait for the result and return it.
I tried different approaches like the one proposed by @jfmnet but it didn't work for me and the app continues crashing.
Trying and experimenting other approaches I find one that it will works for me and consists to open the dialog in another thread, started as Single Thread Apartment and wait for the completion.
public string OpenDialogFile(string filters = null, string title = null)
{
string filePath = null;
Thread thread = new Thread(() => {
using (OpenFileDialog openDialog = new OpenFileDialog())
{
openDialog.Filter = filters ?? "All Files|*.*";
openDialog.Title = title ?? @"Select file";
openDialog.FilterIndex = 0;
openDialog.RestoreDirectory = true;
if (openDialog.ShowDialog() == DialogResult.OK)
{
filePath = openDialog.FileName;
}
}
});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
thread.Join();
return filePath;
}Later you can call that method where it is needed to open a file.
private void CoreWebView2_WebMessageReceived(object sender, CoreWebView2WebMessageReceivedEventArgs e)
{
string msg = e.TryGetWebMessageAsString();
if (msg == "Open Dialog")
{
string file = OpenDialogFile();
doWork(file);
}
}
