OpenLayer (v5.3.0) on the webBrowser of Visual Studio 2017 (vb.net) causes a script error on the Geographical Survey map.

I get a script error when I try to display a map of the National Geographic Agency in OpenLayer using VB.NET's webBrowser control.I captured two script error screens and one error screen during debugging, so could you please let me know?I have confirmed that it was displayed in html format.Thank you for your cooperation.

WebBrowser controls work in IE7 mode by default for compatibility with (and IE7 mode can be dropped to IE5 mode depending on content).

You can change the operating mode by setting the following registry before loading the WebBrowser coat role:

HKEY_LOCAL_MACHINE(or HKEY_CURRENT_USER)
   SOFTWARE
      Microsoft
         Internet Explorer
            Main
               FeatureControl
                  FEATURE_BROWSER_EMULATION
                     contoso.exe=(DWORD)00009000

The contoso.exe part specifies the executable name, and the 00009000 part specifies the IE version that you want to work with.For example, if you want to operate in IE11 mode, use decimal 11000.
