How can I implement caching in ASP.NET Core?

You can implement caching in ASP.NET Core using the built-in caching services. Would you like to know about in-memory caching or distributed caching?

Let's start with in-memory caching.

In-memory caching stores data in the memory of the web server. You can use IMemoryCache to add and retrieve cached items. Do you want a code example?

Yes, please provide a code example.

Here's a simple example:

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 some data"; // Simulate data retrieval
            _cache.Set("myData", data, TimeSpan.FromMinutes(5));
        }
        return Ok(data);
    }
}

This code checks if the data is in the cache and retrieves it if available, otherwise, it sets it.
