AWS Secrets Manager's built-in caching client for .NET (`SecretsManagerCache`) reduces redundant API calls by storing secrets locally for a configurable TTL. A step-by-step walkthrough covers creating a secret via CLI, setting up a .NET console app, adding the `AWSSDK.SecretsManager.Caching` NuGet package, and configuring the cache with a custom TTL and version stage. The demo illustrates that a cached secret is served locally even when the network is disconnected, as long as the TTL hasn't expired.
