How can I improve caching performance in ASP.NET Core?

How can I improve caching performance in ASP.NET Core?

You can improve caching performance in ASP.NET Core by using in-memory caching, distributed caching, and optimizing cache expiration.

What are the differences between in-memory and distributed caching?

In-memory caching stores data in the server's memory, while distributed caching stores data across multiple servers, allowing for scalability.

Can you give me an example of implementing in-memory caching?

Sure! You can use the IMemoryCache interface to store and retrieve data. Here's a simple example:

public class MyService {
    private readonly IMemoryCache _cache;

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

    public string GetCachedData() {
        if (!_cache.TryGetValue("myKey", out string cachedData)) {
            cachedData = "This is some data";
            _cache.Set("myKey", cachedData, TimeSpan.FromMinutes(5));
        }
        return cachedData;
    }
}

What are some best practices for cache expiration?

Best practices include setting appropriate expiration times, using sliding expiration, and regularly monitoring cache performance.
