GAC and FileNotFoundException Can someone help?able to successfully get it working for my asp.net application. The dll is loading from the GAC with correct version and I can verify it from Output window of VS.Net IDE. I can change the policy and it works because I can see the oldversion is redirected to newVersion. The problem is- unless I copy the dll in the bin directory of the application [from where it referenced by other components of the application] I get FileNotFoundException. This entirely defeats the purpose of have the dll in the GAC. I have tried the codebase but asp.net always probes the dll in the temporary directory like the one below- Attempting download of new URL file:///C:/WINDOWS/Microsoft.NET/Framework/v1.1.4322/Temporary ASP.NET Files/iisvirtualpathname/c6b755e3/7450c22c/DataAccess.DLL ...etc. So, my question is why am I getting the file not found exception while the file is already loaded from GAC? Am I missing something? I would appreciate your comments. Thanks, Prodip Saha Have you set the "Copy Local" property of the assembly reference to False?

Yes, Local Copy is set to False.

I have tried it but it did not help- <assemblies> <add assembly="Data.Access,Version=1.0.1902.19083,Culture=neutral,PublicKeyToken= afe57206630e2fsd" /> <add assembly="Interface.Data.Access,Version=1.0.1902.19082,Culture=neutral,Publi cKeyToken=afe57206630e2fsd" /> </assemblies> Will be taking your answer.

non-strong named version of the same dll. I mean the assembly menifest of the ParentAssembly does not have a publickeytoken defined for the Dependent assembly. Example- //ildasm.exe>open>ParentAssembly.dll >manifest ..assembly extern System.Data { .publickeytoken = (B7 7A 5C 56 19 34 E0 89 ) // .ver 1:0:5000:0 } ..assembly extern Data.Access { .ver 1:0:1502:29024 //publickeytoken is not there because I did not recompile the ParentAssembly.dll } I applied the strong name and installed in the GAC at a later time. Does this make any difference?

rebuild all the components (used by the app) with the strong named version of the dataaccess dll and all works fine. I don't have to copy dll in the bin directory anymore. The dll can be in the bin directory during the development time just for adding references. However, the framework will use the one from the GAC. Thanks you all for contributing to this thread.
