Introducing the IE Diagnostics Adapter for third party developer tools

For several releases, Internet Explorer has had diagnostic tools that help developers debug visual issues, find JavaScript bugs, and profile Web sites. These tools have shipped both in the browser as the F12 Developer Tools as well as in Visual Studio. In the interest of making the modern Web "just work" for everyone, today we're announcing an open-source, experimental adapter for Internet Explorer that we're developing to contribute to a wider and more diverse tooling ecosystem across browsers. Right now we’ve targeted the adapter at Internet Explorer 11, but we intend to update it to work with Project Spartan in a future release.
