What is in-memory caching in ASP.NET Core?

In-memory caching in ASP.NET Core allows you to store data in memory for quick access, improving performance.

How do I implement in-memory caching in my ASP.NET Core application?

You can implement it by adding the Microsoft.Extensions.Caching.Memory package and configuring it in the Startup.cs file.

Can you give me a code example of using in-memory caching?

Sure! Here's a simple example:

public void ConfigureServices(IServiceCollection services) {
    services.AddMemoryCache();
}

public class MyController : Controller {
    private readonly IMemoryCache _cache;

    public MyController(IMemoryCache cache) {
        _cache = cache;
    }

    public IActionResult GetData() {
        if (!_cache.TryGetValue("myData", out string data)) {
            data = "This is cached data";
            _cache.Set("myData", data, TimeSpan.FromMinutes(5));
        }
        return Ok(data);
    }
}

What are the benefits of using in-memory caching?

The benefits include faster data retrieval, reduced database load, and improved application performance.
