Please provide a more detailed example. When and on what thread are you calling the method?

Hi,
Thank you for response!
Here is an example:
https://github.com/Pethical/CefSharp.MinimalExample/blob/362befd55337578086c56f2904b78cc52a51bc35/CefSharp.MinimalExample.WinForms/BrowserForm.cs#L180

On the main thread. On menu item click.

As per the documentation you can only call GetVisibleNavigationEntry on the CEF UI thread.

http://cefsharp.github.io/api/75.1.x/html/M_CefSharp_IBrowserHost_GetVisibleNavigationEntry.htm

You can use http://cefsharp.github.io/api/75.1.x/html/P_CefSharp_Cef_UIThreadTaskFactory.htm to access the CEF UI thread.

An exception will now be throw when calling from the incorrect thread, relevant commit 99c177a

Thank you!
