Annotation that indicates a resource should use a specific container registry as its default target.

## Definition

```csharp
namespace Aspire.Hosting.ApplicationModel;

public sealed class RegistryTargetAnnotation
    : Aspire.Hosting.ApplicationModel.IResourceAnnotation
{
    // ...
}
```

This annotation is automatically added to resources when a container registry is added to the application model. It provides a default registry for resources that don't have an explicit [ContainerRegistryReferenceAnnotation](/reference/api/csharp/aspire.hosting/containerregistryreferenceannotation.md).
