Question 1

How do I create my first ASP.NET Core web API?

Accepted Answer

Use the .NET CLI to run 'dotnet new webapi' for a scaffolded project, then follow the getting started guide on Microsoft Learn for step-by-step instructions on building and running it locally.

Question 2

ASP.NET Core vs Node.js: which is better for high-performance APIs?

Accepted Answer

ASP.NET Core often excels in throughput and scalability for CPU-intensive tasks due to .NET's optimized runtime, while Node.js might be preferred for I/O-bound applications with its event-driven model; benchmark based on your specific use case.

Question 3

What's the easiest way to deploy ASP.NET Core to AWS or Azure?

Accepted Answer

For Azure, use Azure App Service with built-in integration; for AWS, containerize with Docker and deploy to ECS or use Elastic Beanstalk, leveraging ASP.NET Core's cloud-optimized features for smooth deployment.

Question 4

How does ASP.NET Core handle database connections and ORM?

Accepted Answer

It integrates seamlessly with Entity Framework Core for ORM, supporting multiple databases, and includes dependency injection for managing connections, making data access straightforward but requiring setup.

Question 5

Can I use ASP.NET Core for building real-time chat apps?

Accepted Answer

Yes, via SignalR, which provides built-in support for WebSockets and other transports, but it requires additional configuration and scaling considerations for production environments.

Question 6

What are the licensing costs for using ASP.NET Core in production?

Accepted Answer

ASP.NET Core is MIT-licensed and free to use, even commercially, but hosting and associated services like Azure may incur costs, so budget for infrastructure separately.
