NavigationStarting Event does not fire

[NguyenDuyDuc1995]

Hi,

I have two cases:
Case 1:

• My laptop is connected to the internet.
• I installed visual studio 17.4.3, WebView2 SDK, Edge Runtime, ...
• I created a project, created a webview2 control, set "https://google.com" in "Source" field.
• Then I debug and the program run well. NavigationStarting Event fired normally.

Case 2:

• My PC at my workplace can not connect to the internet because of my company rules.
• So I download full visual studio 17.3.3, WebView2 SDK, Edge Runtime from my home and installed in my company. Everything is ok.
• I created a project, created a webview2 control, set "http://mycompany.net" in "Source" field.
• Then I debug and the program run but webview2 does not show anything. I checked by access via Edge, the URL is ok.
• I checked events. I saw when program run, NavigationStarting Event did not fire.

Please, check and help me.
Thanks

I checked and found that:

About Case 1:

• In CoreWebView2InitilizationCompleted Event, webView2.coreWebView2 Object exists then finishing this event.
• Then I checked at other events, webView2.coreWebView2 Object still exists.

About Case 2:

• In CoreWebView2InitilizationCompleted Event, webView2.coreWebView2 Object exists then finishing this event.
• Then I checked at other events, webView2.coreWebView2 Object is null.
  => Why?

Please check and help me to fix that.
Thanks
