Make sure that the rebuilt assembly has the correct evidence to be trusted by your deployed solutions, such as a strong name or signature.

Use the Publish Wizard to deploy the assembly. For more information, see How to: Deploy Solution Files Using the Publish Wizard.

The assembly is deployed to a folder at the same directory level as the old assembly, but with an incremented version number. For more information, see Deploying Document-Level Customizations and Deploying Application-Level Add-ins.

If necessary, make changes to security policy so that each end user can run the solution. For more information, see Security Requirements to Run Office Solutions.

The next time an end user uses your solution, the deployment manifest automatically redirects the document or add-in to use the updated assembly. For more information, see Application and Deployment Manifests in Office Solutions.
