winforms - is the c# webbrowser reliable? -

-

i try attaching custom document events fire sometime; don't.

worse, here scenario can test. not sure if os problem. win7 machine, , has ie 11 installed.

i start localhost python web server , serve static web page:

c:\code\forex> python -m simplehttpserver 4542

and try load above web page in webbrowser control. form's code follows:

using system; using system.diagnostics; using system.windows.forms;  namespace winformwebbrowser {     public partial class form1 : form     {         public form1()         {             initializecomponent();         }          private void form1_load(object sender, eventargs e)         {              webbrowser1.documentcompleted += webbrowser1_documentcompleted;                         webbrowser1.navigate("http://localhost:4542");          }          void webbrowser1_documentcompleted(object sender, webbrowserdocumentcompletedeventargs e)         {             if (webbrowser1.readystate == webbrowserreadystate.complete)             {                 debug.print("ready");             }         }     } }

i ready message. once close form, local web server broken result.
