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?
This question is related to
c#
webbrowser-control
Rather than changing the RegKey, I was able to put a line in the header of my HTML:
<html>
<head>
<!-- Use lastest version of Internet Explorer -->
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<!-- Insert other header tags here -->
</head>
...
</html>
Visual Basic Version:
Private Sub setRegisterForWebBrowser()
Dim appName = Process.GetCurrentProcess().ProcessName + ".exe"
SetIE8KeyforWebBrowserControl(appName)
End Sub
Private Sub SetIE8KeyforWebBrowserControl(appName As String)
'ref: http://stackoverflow.com/questions/17922308/use-latest-version-of-ie-in-webbrowser-control
Dim Regkey As RegistryKey = Nothing
Dim lgValue As Long = 8000
Dim strValue As Long = lgValue.ToString()
Try
'For 64 bit Machine
If (Environment.Is64BitOperatingSystem) Then
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION", True)
Else 'For 32 bit Machine
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", True)
End If
'If the path Is Not correct Or
'If user't have priviledges to access registry
If (Regkey Is Nothing) Then
MessageBox.Show("Application Settings Failed - Address Not found")
Return
End If
Dim FindAppkey As String = Convert.ToString(Regkey.GetValue(appName))
'Check if key Is already present
If (FindAppkey = strValue) Then
MessageBox.Show("Required Application Settings Present")
Regkey.Close()
Return
End If
'If key Is Not present add the key , Kev value 8000-Decimal
If (String.IsNullOrEmpty(FindAppkey)) Then
' Regkey.SetValue(appName, BitConverter.GetBytes(&H1F40), RegistryValueKind.DWord)
Regkey.SetValue(appName, lgValue, RegistryValueKind.DWord)
'check for the key after adding
FindAppkey = Convert.ToString(Regkey.GetValue(appName))
End If
If (FindAppkey = strValue) Then
MessageBox.Show("Registre de l'application appliquée avec succès")
Else
MessageBox.Show("Échec du paramètrage du registre, Ref: " + FindAppkey)
End If
Catch ex As Exception
MessageBox.Show("Application Settings Failed")
MessageBox.Show(ex.Message)
Finally
'Close the Registry
If (Not Regkey Is Nothing) Then
Regkey.Close()
End If
End Try

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.
var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";
using (var Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true))
Key.SetValue(appName, 99999, RegistryValueKind.DWord);
According to what I read here (Controlling WebBrowser Control Compatibility:
What Happens if I Set the FEATURE_BROWSER_EMULATION Document Mode Value Higher than the IE Version on the Client?
Obviously, the browser control can only support a document mode that is less than or equal to the IE version installed on the client. Using the FEATURE_BROWSER_EMULATION key works best for enterprise line of business apps where there is a deployed and support version of the browser. In the case you set the value to a browser mode that is a higher version than the browser version installed on the client, the browser control will choose the highest document mode available.
The simplest thing is to put a very high decimal number ...
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.

{
//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).
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
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.
I know this has been posted but here is a current version for dotnet 4.5 above that I use. I recommend to use the default browser emulation respecting doctype

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

just adding the following to your html does the trick no need for registry settigns
