I recently installed an assembly in the GAC and now I am having some trouble
finding it. This assembly defines some TraceListeners that I am using for
logging in our app. The application configuration file contains the following
lines the assembly is ErrorLog:

<trace autoflush="true" indentsize="4">
<listeners>
<add name="debugOut" type="System.Diagnostics.DefaultTraceListener" />
<add name="consoleOut" type="visa.dps.ppc.DynamicFileTraceListener,
ErrorLog" initializeData="ApplicationServer.log" />
<add name="eventOut" type="visa.dps.ppc.EventTraceListener,
ErrorLog" />
<remove name="debugOut" />
</listeners>
</trace>

I look in the GAC and I see

ErrorLog, Version=2.5.4.0, Culture=neutral, PublicKeyToken=33fcdc7f7eb6be4b,
Custom=null

When I run one of my apps that has a configuration file that contains the
lines above, I get:

Configuration exception during setup: Couldn't find type for class
visa.dps.ppc.DynamicFileTraceListener, ErrorLog.

Any idea as to what I am doing wrong?

The TraceListener or the class that is derived from TraceListener is in the
ErrorLog assembly and that as I have indicated is in the GAC. I have verified
this. It seems that the process that parses the configuration file uses a
different algorithm to find an assembly than "normal" it does not seem to be
looking in the GAC for the assembly. Any ideas on how to force the
configuration to look in the GAC?

Thanks again.

Matt,

First, thank you for your reply.

I tried adding a version and public key token and I get the same error which
I have copied below.

Any more suggestions.

Kevin
