Why should you care?

Interviewers and production teams expect you to explain Connection Pooling in ASP.NET Core Web API clearly — not just copy code from Stack Overflow.

See it live — copy this example

Create a Web API (dotnet new webapi), paste the example, run dotnet run, test in Swagger.

// Connection Pooling in ASP.NET Core Web API — ShopNest.API
[ApiController]
[Route("api/[controller]")]
public class DemoController : ControllerBase
{
    [HttpGet]
    public IActionResult Get() => Ok(new { topic = "Connection Pooling in ASP.NET Core Web API" });
}

Run Example »

Edit the code and click Run — like W3Schools Try it Yourself.

What happened?

• Study the example line by line.
• Each part connects to Connection Pooling in ASP.NET Core Web API.
• Edit one line, run dotnet run, and test in Swagger to see what changes.

Try it yourself

1. Read what Connection Pooling in ASP.NET Core Web API means in the introduction.
2. Type the example in ShopNest.API — do not only copy-paste.
3. Test the endpoint in Swagger or curl.
4. Change a route URL or DTO property and save — test again in Swagger or curl.
5. Return the wrong status code on purpose (404 instead of 200) and see what the client shows.

Remember

You learned what Connection Pooling in ASP.NET Core Web API is and when to use it. You ran or traced working API code. Move to the next lesson when you can explain it in your own words.
