Outlook Addin Updating - Replacing DLL sufficient?

Working on an outlook addin and I was wondering if manually replacing the compiled DLL on a target machine is sufficient when I decide to update my addin ? is that practice even valid for stability ?

on some minor changes i did to my addin for tests, It seemed to work, even without changing the manifest, or re-deploying but I'm not sure it will still work if the project changes from end to end - Like, is it possible to take a whole different addin dll, and simply place it instead of a dll that is already installed - and walla ? does its manifest even acknowledge the content of the dll or simply point to it?

Yes, as long as you do not change the addin's class name.

Theoritically, you can replace the add-in assembly with a new one. But the host application should be closed at that time to let you delete/overwrite an existing file. Be aware, the Trust center settings in Outlook can be adjusted to load only signed with a digital signature assemblies. In that case your add-in will not be loaded by the host applications.

Consider using ClickOnce for updating add-ins on the fly. See Deploying an Office Solution by Using ClickOnce for more information.
