## What is **HttpClient** in C#?

**HttpClient** — The .NET class your C# code uses to call a web API: it sends GET, POST, PUT and DELETE requests and gives back the responses. Create one and reuse it, rather than one per request.

```csharp
HttpClient client = new() { BaseAddress = new Uri("http://localhost:5000/") };
List<Product>? products = await client.GetFromJsonAsync<List<Product>>("api/products");
Console.WriteLine(products?.Count);
```

## In a sentence

- “Our console app uses **HttpClient** to read products from the API.”
