Trying to create a certificate using Azure Classic, but can't get my code to compile policy is an object created from CertificateCertificatePolicyArgs. Have also tried wrapping it in an Output.Create Cannot implicitly convert type 'Pulumi.Output<Pulumi.Azure.KeyVault.Inputs.CertificateCertificatePolicyArgs>' to 'Pulumi.Input<Pulumi.Azure.KeyVault.Inputs.CertifiateCertificatePolicyArgs>' I'm using the C# .NET SDK

var certificate = new Certifiate($"cer-{platform}-sp-{stackName}", new CertifiateArgs
        {
            KeyVaultId = vault.Id,
            CertificatePolicy = policy
        });

There is an implicit conversion defined for that, so not sure why it's not being invoked but try adding an explicit cast

(Pulumi.Input<Pulumi.Azure.KeyVault.Inputs.CertifiateCertificatePolicyArgs>)policy

and see if that works?
