What are ASP.NET Core APIs and how do I create one?

ASP.NET Core APIs are web services built using the ASP.NET Core framework. They allow you to create RESTful services that can be consumed by various clients. To create one, you typically start by setting up a new ASP.NET Core project, defining your models, and then creating controllers to handle HTTP requests.

Can you walk me through the steps to set up a new ASP.NET Core API project?

Sure! First, install the .NET SDK. Then, open your terminal and run dotnet new webapi -n YourProjectName. This creates a new API project. Next, navigate to the project folder and run dotnet run to start the server.

What are controllers in ASP.NET Core APIs?

Controllers in ASP.NET Core APIs are classes that handle incoming HTTP requests. They contain action methods that respond to specific routes and return data, typically in JSON format.

How do I test my API once it's set up?

You can test your API using tools like Postman or curl. Simply send requests to the endpoints you've defined and check the responses.
