I just got couple errors by using ClickOnce to publish my app:

Cannot publish because a project failed to build.
SignTool reported an error ‘Failed to sign bin…

This most likely means that you have a “Sign the ClickOnce Manifests” checkbox checked in “Signing” Tab of your project properties and your certificate has expired.

To resolve this:

• Right click on project in VS 2005 Solution Explorer and choose properties.
• Go to “Signing” Tab,
• Click on “Create Test Certificate”, make up a password and enter it.
• Now you can go back to “Publish” Tab and publish your app.
