The root certificate of the signature in the app package must be trusted

[mousumih]

I am able to create the .appx file, but when I run the Add-AppPackage getting the error: Deployment failed with HRESULT: 0x800B0109, A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. I created the certificate as in README:

1. In VS, open DistroLauncher-Appr/Mydistro.appxmanifest
2. Select the Packaging Tab
3. Select Choose Certificate
4. Click the configure certificate drop down and select create test certificate.

How do I ensure that the certificate is trusted?
