I had, however like I mentioned in my earlier post I was unsure about having the assembly name and namespace the same. Have changed these to be different in the external library project and I’ve got a bit further, it’s now giving me a COMException error specific to the external library functionality. Off-topic for here so I’ll take further investigation offline. J
Simple in the end, thanks for everyone’s help!

A tempting approach to install the external one separately, but I think in my case it'd be ideal to deploy them together. The external one is just a library that would never be used as a feature on its own, it would only be used when packaged with something else, a web part/workflow/something. I see where you're coming from though, I'll keep it in mind as an alternative. Cheers.

I wouldnt deploy the external reference assembly with your solution but instead install them separately (if there is installation for it) but as jeremy suggested you can add the safe control entry from your deployment, but that's just me.

Copy Local is set to true on my reference and it does indeed deploy both my web part and referenced assembly to c:\windows\assembly\.

Also found in SP log: http://server/chris/default.aspx - An unexpected error has been encountered in this Web Part. Error: This page has encountered a critical error. Contact your system administrator if this problem persists. which unfortunately is no more exciting than what I’m seeing on the page. Have followed this post to turn on extra debug info, am now seeing this on page: Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported.

Both assemblies now have <SafeControl> entries and are in c:\windows\assembly\. In my external library, my assembly name is the same as my default namespace, is this allowed/problematic? Kind regards, Chris From: [email protected] [mailto:[email protected]] On Behalf Of Jeremy Thake Sent: Tuesday, 28 July 2009 3:01 PM To: [email protected] Subject: RE: Web part with dll reference So are you using the VSeWSS 1.3 CTP when you say Visual Studio projects? I’m assuming you must be using a WSP if its automatically adding the SafeControl entry. The reason you’re probably getting this error is because you need to ensure you deploy the external library with the package. To do this, ensure you have Copy Local set to true in the properties. If it’s VSeWSS you’re using, you can check the manifest.xml file and see whether an Assembly element has been added for it. Also you can check it’s deployed by going to c:\windows \assembly and ensuring the dll is in there ;-) Jeremy Thake Readify | Senior Consultant M: +61 400 767 022 | E: [email protected] | W: www.readify.net From: [email protected] [mailto:[email protected]] On Behalf Of Chris Milne Sent: Tuesday, 28 July 2009 12:41 PM To: [email protected] Subject: Web part with dll reference Afternoon all, I’m developing a web part in which I would like to reference functionality that exists in one of our other company Visual Studio projects (.net assembly/dll). I’m having trouble doing this and hoping someone can point me in the right direction J I’ve created a simple VS web part project which works if I deploy it just by itself (not using the library functionality). I then added a reference to my dll, added a ‘using’ to import the namespace into my code (if I deploy again at this point it still works), but if I add one line of code that uses the external library into CreateChildControls() and deploy, I get a generic ‘Error An Unexpected error has occurred’ message on a page the webpart exists on. Visual Studio is automatically adding a <SafeControl Assembly=..> to my web.config for my web part assembly but not the external library assembly, do I need to add that? Both assemblies are automatically being added to the GAC. Any help is appreciated!
