Hi #docs hopefully this is the right place to report this. There seems to be a small discrepancy in the Azure B2CTenant resource C# reference page (https://www.pulumi.com/docs/reference/pkg/azure-native/azureactivedirectory/b2ctenant/#create-tenant). Name and Tier inputs should be:

Name =  AzureNative.AzureActiveDirectory.B2CResourceSKUName.Standard,
                Tier = AzureNative.AzureActiveDirectory.B2CResourceSKUTier.A0,

instead of raw string I believe.
