Can't reference Assemblies in GAC?

[Nick]

I've just created a simple class library, gave it a strong name using
sn.exe, then copied it to c:\winnt\assembly directory. I then created an
ASP client that reference that assembly. The client works only works if I
have the assembly under the ASP client's \bin directory, even though it's
also in GAC. Does anyone know what the problem is?

I got the following error:

File or assembly name <xxxx>, or one of its dependencies, was not found.

The assembly load trace does not seem to include the directory
"c:\winnt\assembly". Does it not always look for the assembly in GAC?

Thanks in advance.

Hi

Try this out

a) Use th GACUtil utility to register in the GAC

b) more important(and believe me, many have had this
problem), is the way u are referrring to the GAC Assembly
in ur aspx. If u are just giving the assembly name, then
u need to have a copy of that assembly in ur bin dir. If
u want to access the GAC based assembly, then u need to
give the full identity(Name+Version+Culture+Public Key).

For example, while using Microsoft IE Web Controls,
If u refer it in ur aspx as
<%@ register TagPrefix="iewc"
Namespace="Microsoft.Web.UI.WebControls" Assembly
="Microsoft.Web.UI.WebControls" %>
and it forced me to have a local copy

U change it to
<%@ Register TagPrefix="iewc"
Namespace="Microsoft.Web.UI.WebControls"
Assembly="Microsoft.Web.UI.WebControls, Version=1.0.2.226,
Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>

and it will pick up perfectly from the GAC.

The reason is that to use any GAC based assembly u need to
provide the full identity

hope this helps

regards,

sr

Fixed. Thanks.

It looks like I had to copy the dll within the production server to GAC.
What I did before was coping the dll across the network.

Thank for the response.

Not sure if you got a response elsewhere. Anyways, an attempt will be made
to look in the GAC, only if you reference the assembly by the full name -
like so "MyCo.MyAssembly, Version=1.0.1175.28478,
Culture=neutral,PublicKeyToken=5378d68701e60agd"
If you have partial references and don't (cannot) want to change, you can
use qualifyAssembly element in Web.Config to redirect partial-name assembly
requests to full-name requests which then get redirected to GAC.
