Native Ahead-of-Time Deployments

For Native Ahead-of-Time (AOT) deployments, you need to use the NatsConnection class directly. This is because the NatsClient class uses reflection to set up the ad hoc JSON serializers, which is not supported in AOT scenarios.

If you started with the NatsClient class and need to switch to NatsConnection, you can do so without any changes to your code because both classes implement the INatsClient interface.

NuGet packages that are compatible with AOT publishing are:

Note

For dependency injection in AOT scenarios, use NATS.Client.Hosting (with its AddNats() method) instead of NATS.Extensions.Microsoft.DependencyInjection. The latter depends on NATS.Client.Simplified which includes the ad hoc JSON serializer and is not AOT-compatible. See Dependency Injection for a full comparison of the two DI packages.
