Installing Side-by-side Assemblies as Shared Assemblies
To install a side-by-side assembly as a shared assembly
Sign and create a catalog for the files in the assembly.
Files must be signed to install them as side-by-side assemblies. For more information, see Creating Signed Files and Catalogs.
You should install shared side-by-side assemblies as components of a Windows Installer package. This can be the same installation package used to install or update your application. If the shared assembly is shipped as part of multiple applications, you should provide a merge module that can be incorporated into these applications' installation packages and create a catalog for the files in the assembly.
