VSTO add-in with multiple assemblies

I just found a solution to an issue which has been bothering me for a while. The reference article by Microsoft which describes how to deploy a Visual Studio 2005 Tools for Office solution using Windows Installer (a life-saver) doesn’t say anything about how to grant trust to multiple assemblies. This is a problem if you want to use satellite dlls in your add-in.

I figured out a workaround a while back, but I wasn’t convinced this was a good solution. Today, I came across this thread, where the second post (by Lex007) describes a simple way to do that, by modifying the SetSecurity project. Instead of passing only one dll, the tweak allows to pass a comma-separated list of dlls. I just tried it out, and it works like a charm.

Do you have a comment or a question?
