IDistributedCache
IDistributedCache is a .NET interface that defines operations for storing and retrieving data through a distributed cache provider.
Building Web APIs with ASP.NET Core
IDistributedCache is the .NET abstraction for storing and retrieving cached data through an external distributed cache provider.
- How it is used
- Supports shared server-side caching for ASP.NET Core applications running across multiple web servers.
- How deep it goes
- Explains provider selection, registration, typed JSON extensions, dependency injection, cache keys, expiration, and controller usage.
- Examples
- Uses SQL Server configuration, DistributedCacheExtensions, and a MechanicsController cache around filtered and paged database results.
- What you can do after
- Apply it via ASP.NET Core dependency injection to configure a provider and cache serialized application results.

Pro ASP.NET Core 7, Tenth Edition
IDistributedCache is a .NET caching abstraction for storing and retrieving byte-array values shared across application requests and potentially across application instances.
- How it is used
- Caches calculated endpoint values across requests without binding the endpoint to a particular cache implementation.
- How deep it goes
- Works through lookup, write, expiry, implementation registration, and persistent SQL Server setup; does not examine cache-provider internals.
- Examples
- Uses a `/sum/{count}` endpoint, an in-memory cache, and a SQL Server cache table to make reuse and persistence observable.
- What you can do after
- Apply it via ASP.NET Core service registration and string cache methods to reuse calculated values and configure their expiry.
