eShopOnContainers is a cross-platform .NET sample application demonstrating microservices architecture and containerized deployment patterns. Built with .NET 7, the application runs on Linux, Windows, and macOS, supporting multiple development environments including Visual Studio, Visual Studio for Mac, and CLI-based tools with Docker CLI, dotnet CLI, VS Code, or other code editors. The project showcases how to build and deploy distributed systems using Docker containers and Azure Kubernetes Services, making it a practical reference implementation for developers learning cloud-native .NET development.
The repository implements several advanced architectural patterns and design principles. Domain-Driven Design forms the foundation of the application structure, with explicit support for DDD patterns throughout the codebase. The architecture incorporates CQRS (Command Query Responsibility Segregation) patterns for separating read and write operations, event-driven design for asynchronous communication between services, and REST API endpoints for service-to-service and client-to-service communication. These patterns work together to create a scalable, maintainable system that demonstrates best practices in modern distributed application design.
The microservices approach is central to eShopOnContainers, with the application decomposed into multiple independent services that can be developed, deployed, and scaled separately. Each service runs in its own Docker container, enabling consistent deployment across different environments and simplifying dependency management. The use of Windows containers alongside Linux containers demonstrates the flexibility of the .NET platform and Docker ecosystem. The application's support for Kubernetes orchestration through Azure Kubernetes Services shows how these containerized microservices can be managed and scaled in production environments.
The project covers a comprehensive technology stack relevant to modern .NET development. Beyond the core microservices and containerization aspects, the repository includes Single Page Application (SPA) implementations and demonstrates integration with Xamarin for mobile development, showing how a microservices backend can support multiple client types. The architecture documentation and code examples serve as educational material for understanding how to structure complex applications using contemporary patterns and technologies.
As of November 2023, eShopOnContainers transitioned to read-only archive status, with active development moving to the dotnet/eShop repository. The original code remains accessible in the dev branch for reference purposes. This transition reflects the project's evolution from a standalone sample application to an officially maintained reference implementation within the broader .NET ecosystem. The repository continues to serve as a valuable learning resource for developers studying microservices architecture, containerization strategies, and cloud-native .NET application design, even though new development occurs elsewhere. The GitGenius classification data confirms the repository's focus on microservices, containerization, cloud architecture, Docker, ASP.NET Core, event-driven patterns, domain-driven design, CQRS, REST APIs, and Kubernetes, validating its comprehensive coverage of enterprise-grade distributed system patterns and technologies.
