Use an unsigned assembly in a signed project. Impossible?

Hi,

I use in my project a class library which has a reference to Microsoft.Interop.office.interop.word. I need to create/modify word files in my web application based on asp.net.

First time I used Microsoft.Interop.office.interop.word, I tested it with a windows application, my code worked.
Second time, I implemented it in my project...but I hada problem.
My class library is signed with a .snk file.

Microsoft.Interop.office.interop.word is not a signed assembly, so when I compile my class library, it doesn't work correctly...
I didn't find anything about this topic on internet, so maybe someone have an idea for me...^^

thanks

Hi,

I think the problem is not due to you use the unsigned assembly in a signed assembly but you may not build a signed assembly correctly.

This tutorial about how to create a signed friend assembly you may have a check:

And this tutorial about how to sign an assembly with strong name you may see:

I tried that, but it doesn't work..

I'm going to test your first answer...

At this time, my code is :

Class library A which is signed

Class library B which is not signed

Class library B referenced to Microsoft.interop.office.interop.word.

so I think your first link will work...?
