How to implement caching in ASP.NET Core minimal APIs

"ASP.NET Core offers the flexibility to cache server responses on the client (response caching) or on the server (output caching). In addition, you can choose to cache the data in the memory of the application server (in-memory caching), or in an external data store such as Redis or SQL Server (distributed caching), or a combination of both (hybrid caching). We'll examine all of these options here."

"Launch the Visual Studio 2022 IDE. Click on "Create new project." In the "Create new project" window, select "ASP.NET Core Web API" from the list of templates displayed. Click "Next." In the "Configure your new project" window, specify the name and location for the new project. Optionally check the "Place solution and project in the same directory" check box, depending on your preferences."

Caching in ASP.NET Core minimal APIs improves performance and scalability by storing responses or data at various locations. Response caching stores server responses on the client, while output caching stores responses on the server for reuse. In-memory caching keeps data inside application memory for fast access. Distributed caching places cached data in external stores such as Redis or SQL Server to support multi-server deployments. Hybrid caching combines in-memory and distributed techniques for performance and resilience. Visual Studio 2022 and .NET 9 provide the tooling and framework versions used to implement these caching strategies.
