Caching is a superpower that can take your ASP.NET Core application to the next level. Imagine making your app faster, more responsive, and more efficient. It’s like giving your application a turbo boost. In this blog, we’ll explore the world of caching strategies in ASP.NET Core, and I promise, it’s going to be a fun ride!

Let’s Start with a Problem

Imagine you’re the mastermind behind a music streaming service, “TuneMaster.” Your app provides users with access to millions of songs. Every day, thousands of users search for songs, artists, and albums, and your app needs to serve those requests as fast as possible.

The problem is, every search operation requires a complex database query, which can slow down your app. How can you make this process lightning fast and keep users grooving to their favorite tunes?

Enter Caching

Caching is like having a magical storage space where you keep frequently used data. Instead of repeatedly fetching the same data from your database, you can fetch it once, store it in the cache, and reuse it when needed. This is where caching strategies come into play.

Step 1: Set Up Your ASP.NET Core Project

Before we dive into caching, let’s set up an ASP.NET Core project. You can use Visual Studio or your favorite code editor. If you’re new to ASP.NET Core, Microsoft’s documentation provides excellent guidance on getting started.

Step 2: Add Caching to Your Project

In your Startup.cs file, you need to add caching services to your project. ASP.NET Core supports in-memory caching, distributed caching, and more. For this example, we'll use in-memory caching, which is great for development and simple scenarios.

Here’s how you can configure it:

public void ConfigureServices(IServiceCollection services)
{
services.AddMemoryCache();
// Other service configurations...
}

Step 3: Cache Your Data

Now, let’s cache the results of song searches. When a user searches for a song, you can check if the results are already in the cache. If they are, return them; if not, fetch the data from the database, store it in the cache, and then return it to the user.

public async Task<List<Song>> SearchSongs(string…
