Any MVC code is compiled into the SitefinityWebApp
dll, it does not have its own dll.
In terms of modifying the AssemblyInfo
file, it is not recommended to modify the version found here as it could cause problems with upgrades. What I can suggest for you is to use Feather, then you can create your MVC widgets in a separate assembly
that you can use in your project.
I hope this information helps you.
