Edit your ASP.NET code on the fly with Page Inspector
Debugging websites between a client and a server is difficult. Page Inspector is a new tool that brings browser diagnostics tools into Visual Studio and provides an integrated experience across the browser, ASP.NET, and source code. Using Page Inspector, you can see which elements in the source files have produced the HTML markup that is rendered to the browser. Modify CSS properties and DOM element attributes with changes reflected immediately in the browser.
