Learn ASP.NET Core output caching with real C# examples. Speed up API responses dramatically with policies, cache invalidation & Redis. Start caching today! If your API is hitting the database on every single request for data that barely changes, you are burning CPU, database connections, and money for nothing. ASP.NET Core output caching is one of the highest-impact, lowest-effort performance wins available in modern .NET: with a few lines of code, you can serve repeat requests in microseconds instead of milliseconds — often cutting response times by 90% or more and slashing database load dramatically. Output caching was introduced in .NET 7 as a first-class middleware and has matured significantly through .NET 8 and .NET 9, gaining built-in Redis support, tag-based invalidation, and clean integration with Minimal APIs and MVC controllers. In this tutorial, you will learn how output caching works, how it differs from response caching (a distinction that confuses even senior d...
