You use Visual Studio .NET to create several Windows-based applications. All use a common class library assembly named ABCCustomers. You deploy the application to client computers on your company intranet. Later, you modify ABCCustomers.Any application that uses version 1.0.0.0 must now user version 2.0.0.0. What should you do?

Publisher Policy assemblies redirect old assembly versions to new versions, allowing centralized control over version binding. By deploying a publisher policy, all applications using the old version automatically redirect to the new version without modifying individual app configs. Machine config affects all assemblies globally, which is too broad. Application config would require updating each application separately. Reference patch is not a valid concept. Publisher policy is the most efficient solution for version redirection.
