Answer Implementing Caching in ASP.NET Core
As an experienced tutor registered on UrbanPro.com specializing in .Net Training and online coaching, I understand the importance of caching in ASP.NET Core. Here's a comprehensive guide on how to implement caching in ASP.NET Core for optimal performance.
Caching is a technique that stores frequently used data in memory to reduce the time it takes to fetch the data when requested. In ASP.NET Core, caching can significantly improve the performance of web applications.
There are two main types of caching in ASP.NET Core:
1. Output Caching:
2. In-Memory Caching:
[ResponseCache] attribute to enable output caching for a specific action or controller.[ResponseCache(Duration = 60, Location = ResponseCacheLocation.Client)] public IActionResult Index() { // Your action logic } In the Startup.cs file, configure the in-memory cache in the ConfigureServices method:
services.AddMemoryCache(); In your controller or service, use IMemoryCache to perform caching operations.
public class MyService { private readonly IMemoryCache _memoryCache; public MyService(IMemoryCache memoryCache) { _memoryCache = memoryCache; } public List<MyData> GetCachedData() { if (!_memoryCache.TryGetValue("MyCachedData", out List<MyData> data)) { // Data not in cache, fetch and set in cache data = GetDataFromDataSource(); _memoryCache.Set("MyCachedData", data, new MemoryCacheEntryOptions { AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(10) }); } return data; } } Set appropriate cache expiration times:
Use cache profiles:
Startup.cs and apply them to controllers or actions.Consider distributed caching:
