How to replace an assembly with strong name

gbzhhu asked
Last Modified: 2013-12-17

I have an winforms app that references an assembly (a dll).  The referenced assembly was built with a strong name and I have the .snk file.  The main application has been deployed to users for many years.  I made a small change to the referenced dll and replaced the older one on the client's machine.  That causes an error (not in my dev environment but on the client PC)

System.IO.FileLoadException: The located assembly's manifest definition with name 'Dbt.WinForms.Controls' does not match the assembly reference.

What do I need to do here?  I thought what I did was sufficient since I strong named the assembly again with the same .snk file as before!
