GeckoWebBrowser crash in anyCPU










0















In a C# .Net 4.7.2 WPF project, I'm loading the GeckoWebBrowser component from a UserControl. I'm using the nuget package id="Geckofx60.64" version="60.0.18" .



My solution and project are configured with "Any CPU" in VS2017.



In order to get the Firefox64 repository, I add the nuget package id="Geckofx60.64.Windows" version="0.7.0".



Everything is OK, then I'm calling an "index.html" page with the following code



public partial class Simulator : UserControl

readonly string indexPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Templates", "index.html");

private GeckoWebBrowser _browser;

public Simulator()

InitializeComponent();
Xpcom.Initialize("Firefox64");

var host = new WindowsFormsHost();
_browser = new GeckoWebBrowser();

host.Child = _browser;
GridWeb.Children.Add(host);


private void Datacontext_ConfigurationChanged(object sender, System.EventArgs e)

Dispatcher.Invoke(() =>
_browser.Navigate(indexPath)
);


private void Simulator_OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)

var datacontext = DataContext as ServicesViewModel;
if (datacontext != null)

datacontext.ConfigurationChanged -= Datacontext_ConfigurationChanged;
datacontext.ConfigurationChanged += Datacontext_ConfigurationChanged;





The logic in my application is to refresh the browser each time I have some changes in my local objects.



Datacontext_ConfigurationChanged will be called for each change.



It's working pretty well except that I can receive this exception randomly during a refresh



"System.AccessViolationException: Attempted to read or write protected memory.."


This exception crashes my app, and I can't find any solution for this exception.
Thank you for your help !

  • I see you're using x64 geckofx binaries, but using AnyCPU. Have you turned off "Prefer 32-bit" in the build settings? Its on by default. If you haven't, its trying to run as 32 bit instead of 64 bit.

  • Hi, thank you, but "Prefer 32-bit" is not checked (for all projects) in build settings.
