ASP.NET Core .NET 10 + Docker + Azure Container Apps | Deploy, Scale & Run APIs in the Cloud

🚀 In this complete hands-on tutorial, we build an ASP.NET Core .NET 10 Web API, containerize it using Docker, push the image to Azure Container Registry (ACR), deploy it to Azure Container Apps, expose it through a public HTTPS endpoint, and configure automatic scaling.

This tutorial is designed for .NET Developers, Azure Developers, DevOps Engineers, Software Architects, Technical Leads, Cloud Engineers, and anyone looking to understand modern cloud-native application deployment.
