I was looking at a recent project that I had downloaded (it happened to be CommunityServer) and bumped into this file. I can't find anything about it in the visual studio help files, and MSDN is just lame....it won't search for "<assembly>" (including the tags). Here's the contents of the file:

<?xml version="1.0"?>

I'd been struggling with ASP.NET and the assembly name when an assembly is compiled dynamically. Is this file a possible solution? Does it have something to do with references or dynamic compilation?
