Tip: To reuse a Webview2 Control from a previously closed window in VB.Net

To reuse a Webview2 control from a previously closed window. (VB.NET Code)

1. Ensure that the Webview2 control in Form2 was initialized from the Form_Main
2. Call Form2 with a check to see if re-initialization is required

Private Sub Form_Main_Load(sender As Object, e As EventArgs) Handles MyBase.Load
     Form2.Webview_Form2.Source = New Uri("about:blank")
End Sub

Private Sub OpenForm2()
     if PreviouslyLoaded = True Then ReinitializeWebView_Form2()
     Form2.WebView_Form2.Source = New Uri("https://www.google.com/")
     PreviouslyLoaded = True
     Form2.Show()
End Sub

Private Async Sub ReinitializeWebView_Form2()
    Await Form2.WebView_Form2.EnsureCoreWebView2Async()
End Sub

I can add to the above suggestion.

I have now found that

Form2.WebView_Form2.Source = New Uri("https://www.google.com/") does work
BUT Form2.WebView_Form2.NavigateTo = "some html code" does NOT work

My personal work around was to create Form2 and the associated WevView2 control dynamically when required then all the resources are released when Form2 is closed.
