So I have an C# Form application that utilizes the web browser component. Apparently Response.Write(Request.Browser.Version.ToString()); returns "7.0" when I visit my test page from the web browser component.

How can I make this web browser component use IE8?

It appears you need to fiddle with the registry as per this article: -

http://blogs.msdn.com/ie/archive/2009/03/10/more-ie8-extensibility-improvements.aspx

To run a WebBrowser control in IE8 Standards Mode, use the following new value into the registry:

[(HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] 
"MyApplication.exe" = dword 8000 (Hex: 0x1F40)

To run in IE7 Standards Mode, use the following registry value:

[(HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] 
"MyApplication.exe" = dword 7000 (Hex: 0x1B58)

For IE8 RTM, we’ve added a new “forced” IE8 Standards Mode value. When an application opts into this mode, the Web Browser control will use the IE8 User-Agent string and Browser Emulation mode strictly. It will also ignore fallback features such as the built-in Compatibility View list and the user-generated Compatibility View list when loading pages. To run in “forced” IE8 Standards Mode, use the following registry value:

[(HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] 
"MyApplication.exe" = dword 8888 (Hex: 0x22B8)

In all of these examples, “MyApplication.exe” refers to the name of your application.
