No valid signing keys found in Keychain

I am learning how to devlop ios apps through Xamarin University. I am running Visual Studio 2017 on Windows 10 but using an imac as a build host. When i build the sample application from a tutorial I get an error message that says "No valid signing keys found in Keychain". It says i need to request a code signing certificate. How can i do this?

'Keychain' is mac/macOS centric. You'll need to ask XU for help with their workflow.
