In order to add the tag you have to control the page so that you can add the tag into your HTML. There are a few things you need in order to use the meta tag and make it work properly: You can also specify a specific version of IE: ДЇor info on all the modes available see this StackOverflow answer.ДЄlternately you can also serve X-UA-Compatible: IE=edge as a raw HTTP header from a Web server, which has the same behavior as the http-equiv meta header. So if you have IE 11 installed that's used, if IE 10 is installed that's used. In this case IE=edge uses the current version of IE that is installed on the machine. Note the header should be the first header so that the engine is applied before any other headers are processed.

Inside of a full document it looks like this:

The tag to use in the header looks like this: By adding a meta tag to the head of the HTML document rendered in the Web Browser Control you can effectively override the IE Rendering engine and specify which version of IE (or the latest version) to use. If you control the content in your Web Browser control by rendering the HTML pages you display yourself, the easiest way to provide later versions of the IE rendering engine is by using the IE Edge mode header. If youвЂ™re building an application that intends to use the Web Browser control for a live preview of some HTML this is clearly undesirable. But the default IE 7 mode doesn't recognize many of these settings resulting in a terrible render mode. behave differently by default, even though thereвЂ™s a CSS reset applied on this page. Not only are the new CSS features missing but the page also renders in Internet ExplorerвЂ™s quirks mode so all the margins, padding etc. Obviously the latter rendering using the Web Browser control in a WPF application is a bit lacking. The the full Internet Explorer the page displays the HTML correctly вЂ“ you see the rounded corners and shadow displayed. One uses Internet Explorer as a standalone browser, and one uses a simple WPF form that includes the Web Browser control. To see what IвЂ™m talking about, here are two screen shots rendering an HTML5 page that includes some CSS3 functionality вЂ“ rounded corners and border shadows - from an earlier post. Using Application specific FEATURE_BROWSER_EMULATION Registry KeysД«ut first lets see the problem more graphically.Using the IE X-UA-Compatible Meta header.The good news is there are a couple of ways to override the default rendering behavior: Behind the scenes all these UI platforms use the same COM interfaces and so youвЂ™re stuck with those same rules. This applies whether youвЂ™re using the Web Browser control in a WPF application, a WinForms app, or FoxPro application using the ActiveX control. This is because the original versions of the ActiveX control used this mode and for backwards compatibility the Control continues this outdated and very HTML5 unfriendly default. Even though we're now up to IE 11 and a reasonably HTML5 compatible browser, the Web Browser Control always uses the IE 7 rendering engine by default. The Web Browser Control allows for an effective way to display HTML in your applications in a way that blends in and becomes part of your application.Д«ut there's a snag: The Web Browser Control is - by default - perpetually stuck in IE 7 rendering mode.

HTML is easy to generate, generally re-usable, and easily extensible and distributable. Even in desktop applications, is often way easier than using labels or edit boxes or even some of the WPF text containers. Whether you're just rendering document content, or you're interacting with rich interactive content, HTML happens to be one of the most common document formats to display or interact with and it makes a wonderful addition to conventional forms based UI. For example Markdown Monster, Help Builder and WebSurge rely heavily on the Web Browser Control to render their document centric or even rich interactive UI (in the case of Markdown Monster which hosts an HTML editor). I use the Internet Explorer Web Browser Control in a lot of my desktop applications to display document content. Updated Aug 26th, 2016 - the original was published in May 2011
