Eclipse Tools for Microsoft Silverlight

I was excited to learn about the eclipse4SL preview for Mac OS X. I wasted no time installing it, which was a snap. I created a sample "hello world" Silverlight project (not a Silverlight web project). I run the project, the test page loads in the browser window (Firefox), and that's it. The .xap is never downloaded or displayed.

I've seen this same behavior when hosting the Silverlight app from IIS 6. The solution to the problem in that case is to add .xap to the mime types in IIS.

Is there something similar I need to do in the Mac world?

Thanks,
