What purpose does the Silverlight.js file serve?

问题

I asked this question this morning. Essentially there's an IE hack in the Silverlight.js file that breaks in...IE9.

The response I got was to get rid of the file altogether which, to my surprise, seemed to work after preliminary testing.

So does this file actually serve a purpose?

回答1:

I believe this was included as a way to launch Silverlight on browsers with an advanced "install" experience, or to show alternative HTML when Silverlight was not installed.
