Hi, This is something you will need to work out yourself. We are not in a position to troubleshoot web pages for our customer. If you suspect the problem is on our side, you can try to isolate the problem to a test project and send the test project to us. See here for more details: https://www.essentialobjects.com/forum/test_project.aspxThanks!

We would like to help but we have thousands of customers and if everyone of them asks us maybe we know something that can help them debugging their application whenever they run into problems while using our product, we would be flooded with such requests and won't be able to function at all. As such we will only investigate if you have already put reasonable efforts on your end and can clearly demonstrate that the problem is related to us. Hope you understand.

There is hardly any difference at all on our part. The core class for EO.WebBrowser is the WebView class. This class load, run and display the page and this class is platform neutral.
Since EO.WebView has to sit somewhere in the UI, it requires a parent window handle. The only difference between WPF and WinForm is how this handle is created since in WPF it has to be created WPF way and in WinForm it has to be created Windows.Forms way. This is what the EO.WebBrowser.Wpf.WebControl and EO.WebBrowser.WinForm.WebControl is for. These two classes provide the "bridge" to integrate the core WebView class with your WPF or WinForm application. The bridge itself does not affect the functionalities since everything is done inside the WebView class. If you don't use Windows.Forms or WPF, you don't even need to those two "bridge" classes and you can just use WebView directly and your web page should still function the same way. So most likely the problem is not related to the difference between Windows.Forms and WPF. It has to be somewhere else in your code. That's why you have to try to isolate the problem in order to find out what triggered the problem first.

I compared code from your WPF and found that exist assigning to e.UseOSHandler = true; in void WebView_LaunchUrl(object sender, LaunchUrlEventArgs e). What is it? Can you provide details?

Hi, See here for more details: https://www.essentialobjects.com/doc/eo.webbrowser.launchurleventargs.useoshandler.aspxSetting this property to true to automatically using the handler registered with the OS to handle the Url. For example, to automatically launch your email program to handle a "mailto:" Url. Thanks
