There was a problem with the original publication of the CLR Symbols for some binaries (mscoree, mscorwks, maybe others). This was causing the profiler to be unable to load symbols for these binaries. The end result was a lot of [mscoree.dll] function names in all profiling reports. I have been informed that these should be up on the public symbol servers very soon (today or tomorrow).
Thanks for your patience.
UPDATE!! This is still broken. More to come....
