I tried all the steps and resolved symbol not loading problem also.

It did not work. After profiling, I see some user23 and iexplore methods which do not have userfriendly names.
Nothing related to silverlight was profiled.

@Oren:
I am also having trouble getting the agcore.dll symbols to load (my functions are showing up, and pdb’s for my assemblies are being loaded — the vsip file is in the output directory of my project, and I am using the MS public symbol server — all the managed symbols are loading fine.

I found a post here: http://social.msdn.microsoft.com/Forums/en-AU/vstsprofiler/thread/d1eab82e-0c28-454e-9d46-92818c606c04 where a Microsoft support person claims that symbols for agcore are not publicly available. Is that correct? I’m afraid I’m not getting much use out of the profiler, because it just says that all of my time is spent in agcore.dll.

Hey Oren,
It looks like I am able to resolve the symbols for all MS symbols except the critical Silverlight ones — is this due to the 64-bit path, or perhaps this version’s symbols haven’t been published yet?

Loaded symbols for C:\Windows\SysWOW64\ntdll.dll.
Loaded symbols for C:\Windows\system32\WINMM.dll.
Failed to load symbols for c:\Program Files (x86)\Microsoft Silverlight\4.0.60531.0\agcore.dll.

Good post – For the single process IE issue, I used Firefox rather than change the registry to hack IE. Finally got meaningful info in my vsp that way.

@Oren Maybe the dlls loaded by add-ons somehow interfere with Silverlight. There are e.g. parts of the regular .NET framework (e.g. C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll and C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscoreei.dll) loaded when add-ons are not disabled. May this be a reason?

@Bernhard
Thanks for the tip – I’ve never seen this one before, but I’ll keep it in mind the next time I run into a dll loading problem. Thanks!

Another Hint: Initially, I didn’t manage to get my dlls loaded into the profiler. It turned out that by disabling all Internet Explorer add-ons except the Silverlight plugin the dlls were found correctly.
