Can't find an assembly in the GAC which application is using

Question

I need to update an assembly that my application is using.

It is a website application referencing the assembly in the GAC via this line in the web.config

<add assembly="dotnetCHARTING, Version=4.3.2721.21869, Culture=neutral, PublicKeyToken=AF2CD47DB69D93BD" />

However I am confused, I cannot find the assembly in C:\Windows\assembly or C:\Windows\Microsoft.NET\Assembly

I have tried looking via the public key and assembly name.

Any ideas?

(Edited - converted web.config line to code sample)

Please confirm that the assembly is in the GAC. Check what application **is** using by attaching debugger and checking list of loaded modules. — Alexei Levenkov, Apr 25 '12 at 15:58

Have you tried using the .NET Fusion Logger? It should tell you the exact path that the assembly was loaded from.

Or just look in the bin folder. If it's not in the GAC it's in one of the other locations searched for assemblies. – Dave Apr 25 '12 at 15:57

What version of .Net are you using? In .Net4, the location of the GAC changed. See this question for more details: .NET 4.0 has a new GAC, why?

Try Create dump or mini dump using process explorer. It will show all the dll's your application is using.
