What is the purpose of the CreateSilverlight.js?

I am trying to get out of browser support working for my Silverlight application and keep bumping into examples that reference CreateSilverlight.js. Looks like it has 开发者_Go百科a variety of options to configure the the Silverlight experience for the end user.

Is this a Microsoft javascript file for Silverlight? If so, where would I find it? I would have expected it to have already been added to my Silverlight project.

Any help would be appreciated!

CreateSilverlight.js is the Silverlight runtime boostrapper. It should be in any new Slivelight project you create in Visual Studio, as long as you've loaded the Silverlight SDK.
