Question

Unable to locate assembly

Asked by: purplesoup

When running my asp.net project I get an error "unable to load (assemblyname)" - looking further at the error message revealed it was looking in my bin folder.

The dll is actually located in another folder which I have referenced both directly under "references" and is also listed in the project properties "reference paths".

I can work around the problem by copying the dll into the bin folder, but I would prefer to not have to do this. How can I get the project to reference the dll outside of the bin folder?

I am using VS 2008, .NET 3.5

You can register it to the GAC of all machines that will be running the software.

Why do you not want it in the bin?  That way you do not have to worry about machine compatibility.

Is that the only option? I thought it would be possible to simply reference another folder.

The reason I don't want them in the local bin folder is because the folder being referenced is regularly updated, so every new solution/project I create would need to regularly copy over the latest dlls into its local bin folder, this takes up disk space, takes time and may be forgotten, leaving a mismatch between the two versions.

Then your best bet is registering it in the GAC.  The only other thing I can think of is to keep it in the bin of a library you can pass along, that way you can just move that dll around, but then it is still a problem I suppose.  Maybe there is another approach that is better?

Perhaps I'm not being clear enough. When I say "running my asp.net project" I am talking about running the website from within Visual Studio in order to debug it. It can locate the assemblies in another folder when building the project, why can't it locate them when debugging it/running it from Visual Studio?

Because when you DEPLOY a web site, it deploys the output of the project, along with any referenced DLLs. Fusion uses a well known pattern for searching for assemblies when loading them. One thing you can do is add a post build event to your project to copy the referenced external assemblies into the bin/debug folder. I use this often for external resources of various types, including scripts.
