Signing ClickOnce Manifests
.NET Framework 2.0
To publish an application using ClickOnce deployment, you must sign the application and deployment manifests for the application with a public/private key pair. The tools for signing a manifest are available on the Signing page of the Project Designer; for more information see Signing Page, Project Designer. Alternatively, you can sign the manifests with a key file during the publishing process, using the Publish Wizard.
