Assembly not found when in GAC

[Web Team]

Hi All,

I recently moved our assembly which stores our 'common' code into the
GAC. I then moved all copies of this assembly out of the /bin folders,
restarted IIS. I get the error below.

This is the first time I have put something into the GAC, from what I
read, the GAC is probed first, before looking to application folders,
so surely my code should load from the GAC, if its not in the app
folders? Or, is the error due to the way we have referenced the
libraries when building (Referenced by project).

Any help/advice on this will be appreciated.

Thanks,

Simon.

Hey,

Is your DLL dependent on another assemly (not in the GAC)?

You need to tell ASP.NET explicitly to look for assemblies in the GAC.
Unlike WinForms application which automatically look in the GAC, ASP.NET
applications do not.

You can do this by adding something like this:

<compilation defaultLanguage="c#" debug="true">

<assemblies>

<add assembly="MyAssembly.MyClass, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"/>

</assemblies>

</compilation>
to web.config. You need to use the strong name for the assembly.
Hope this helps,

Hi Rick,

Thanks for your reply. Couple of questions if you don't mind...

- Do I do this in the web.config for each application?
- I take it I would then have to rebuild all my apps?
- Where do I get the value for the PublicKeyToken attribute?

Cheers!

Simon.
