[BUG] PublishAot = true does not work for Azure.ResourceManager.Dns

[mburumaxwell]

Library name and version

Azure.ResourceManager.Dns 1.1.1

Describe the bug

When PublishAot is set to true, reading DNS records fails. Reading subscription, resource group, and the DNS zone still works.

Traced the bug down to this line:

azure-sdk-for-net/sdk/dns/Azure.ResourceManager.Dns/src/Customization/Models/DnsARecordData.Serialization.cs

Line 179 in 11fa9b7

systemData = JsonSerializer.Deserialize<ResourceManager.Models.SystemData>(property.Value.ToString());

Expected behavior

Ideally, deserializing SystemData should use key values or be skipped (seems to be the case to ResourceGroupResource)

Actual behavior

Exception is thrown:

System.InvalidOperationException: Reflection-based serialization has been disabled for this application. Either use the source generator APIs or explicitly configure the 'JsonSerializerOptions.TypeInfoResolver' property.

Reproduction Steps

Create a console application with AOT enabled or enable AoT in a console application.

var resourceGroupName = "<your-rg-name>";
var zoneName = "contuse.com";
var recordName = "office";

var credential = new DefaultAzureCredential();
var client = new ArmClient(credential);
var sub = armClient.GetDefaultSubscriptionAsync();

Azure.ResourceManager.Resources.ResourceGroupResource resourceGroup;
resourceGroup = await subscription.GetResourceGroupAsync(resourceGroupName, cancellationToken);

DnsZoneResource zone;
zone = await resourceGroup.GetDnsZoneAsync(zoneName, cancellationToken);

var aRecord = await zone.GetDnsARecordAsync(recordName, cancellationToken);
