Use latest version of Internet Explorer in the webbrowser control

Question

The default version of the webbrowser control in a C  Windows Forms application is 7  I have changed to 9 by the article Browser Emulation  but how is it possible to use the latest version of the installed Internet Explorer in a webbrowser control

I was able to implement Luca s solution  but I had to make a few changes for it to work  My goal was to use D3 js with a Web Browser control for a Windows Forms Application  targeting  NET 2 0   It is working for me now  I hope this can help someone else   using System  using System Collections Generic  using System Windows Forms  using System Threading  using Microsoft Win32  using System Diagnostics   namespace ClientUI       static class Program               static Mutex mutex   new System Threading Mutex false   jMutex                  lt summary gt              The main entry point for the application               lt  summary gt           STAThread          static void Main                         if   mutex WaitOne TimeSpan FromSeconds 2   false                                    Another application instance is running                 return                            try                               Application EnableVisualStyles                    Application SetCompatibleTextRenderingDefault false                    var targetApplication   Process GetCurrentProcess   ProcessName     exe                   int ie emulation   11999                  try                                       string tmp   Properties Settings Default ie emulation                      ie emulation   int Parse tmp                                     catch                     SetIEVersioneKeyforWebBrowserControl targetApplication  ie emulation                    Application Run new MainForm                               finally                               mutex ReleaseMutex                                     private static void SetIEVersioneKeyforWebBrowserControl string appName  int ieval                        RegistryKey Regkey   null              try                               Regkey   Microsoft Win32 Registry LocalMachine OpenSubKey   SOFTWARE Microsoft Internet Explorer Main FeatureControl FEATURE BROWSER EMULATION   true                       If the path is not correct or                    if user doesn t have privileges to access the registry                 if  Regkey    null                                        MessageBox Show  Application FEATURE BROWSER EMULATION Failed - Registry key Not found                        return                                     string FindAppkey   Convert ToString Regkey GetValue appName                        Check if key is already present                 if  FindAppkey    ieval ToString                                          MessageBox Show  Application FEATURE BROWSER EMULATION already set to     ieval                       Regkey Close                        return                                        If key is not present or different from desired  add modify the key   key value                 Regkey SetValue appName  unchecked  int ieval   RegistryValueKind DWord                       Check for the key after adding                 FindAppkey   Convert ToString Regkey GetValue appName                     if  FindAppkey    ieval ToString                                          MessageBox Show  Application FEATURE BROWSER EMULATION changed to     ieval      changes will be visible at application restart                                      else                                       MessageBox Show  Application FEATURE BROWSER EMULATION setting failed  current value is      ieval                                               catch  Exception ex                                MessageBox Show  Application FEATURE BROWSER EMULATION setting failed      ex Message                             finally                                 Close the Registry                 if  Regkey    null  Regkey Close                                      Also  I added a string  ie emulation  to the project s settings with the value of 11999  This value seems to be working for IE11 11 0 15    Next  I had to change the permission for my application to allow access to the registry  This can be done by adding a new item to your project  using VS2012   Under the General Items  select Application Manifest File  Change the level from asInvoker to requireAdministrator  as shown below     lt requestedExecutionLevel level  requireAdministrator  uiAccess  false    gt    If someone reading this is trying to use D3 js with a webbrowser control  you may have to modify the JSON data to be stored within a variable inside your HTML page because D3 json uses XmlHttpRequest  easier to use with a webserver   After those changes and the above  my windows forms are able to load local HTML files that call D3

Rather than changing the RegKey  I was able to put a line in the header of my HTML    lt html gt       lt head gt           lt  -- Use lastest version of Internet Explorer -- gt           lt meta http-equiv  X-UA-Compatible  content  IE edge    gt            lt  -- Insert other header tags here -- gt       lt  head gt           lt  html gt    See Web Browser Control  amp  Specifying the IE Version

It is best to force the highest mode possible  That can be accomplished by adding    lt meta http-equiv  X-UA-Compatible  content  IE edge  gt    and it is always good to include the polyfill library in order to support IE    lt script src  https   polyfill io v3 polyfill min js features es6  gt  lt  script gt    before any script

A cheap and easy workaround for it is that you can just put a value which is bigger than 11001 in the FEATURE BROWSER EMULATION key  Then it takes the latest IE that is available in the system
