Dispose error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) #1767

Open fdzatdtv opened 3 years ago

Description The exception occurs within the main UI thread when closing the application or form. There is an older issue (#349) that was closed. But it seems that the bug is still there. The exception happens during Dispose(). Not sure whether this is the first call to Dispose or if it's another call to Dispose. System.Runtime.InteropServices.COMException: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F)

@fdzatdtv Thanks for the bug report Carlos! My guess is that this is from a subsequent call to Dispose. Do you have a sample app or sample code that can reproduce this issue?

fdzatdtv commented 3 years ago

@champnic I've checked our code now. We have a guard in Dispose(bool) which ensures that the underlying Dispose is called only once. Setting our bool flag to true is done in a finally block. So, our guard works even in case of an exception during Dispose().

So, any thoughts why Microsoft.Web.WebView2.Core.Raw.ICoreWebView2.remove_NavigationCompleted is crashing?

champnic commented 3 years ago

What thread is dispose being called on? It needs to be called from the same thread that created the WebView2. Of note, the finalizer often runs on a background thread, so if you are relying on that to call dispose that may be the cause here.

Seeing a similar issue when running a WebView2 control in a panel in Word.

CoreWebView2 members cannot be accessed after the WebView2 control is disposed.

@champnic It is the main thread, not the finalizer thread, where Dispose was called. We've collected more than thousand of the same callstack.

champnic commented 3 years ago

@fdzatdtv And is that the same thread that you created the WebView2 control on? Is this a consistent repro that happens every time you close the form? Is there code you can share or a sample app we can use to try and debug this issue?

fdzatdtv commented 2 years ago

Hi @champnic, since we ship our application built against SDK 1.0.1054.31 we register a lot less exceptions of this kind. But they're not gone. It doesn't happen every time the form is closed. Otherwise we would have massive regristrations. The WebView2 is created in the main thread and the exception callstack is also from the main thread. Unfortunately, we can't share the code nor find a simple app to reproduce the bug.
