.NET Core Microservices Sample

This project consists of multiple (micro-)services based on .NET 5. It's part of a consulting workshop and free to use.

General

This sample is a simplified abstraction of a machine visualization based on a sample machine implementation (simulated via a console application), an ASP.NET Core REST service backend and a HTML frontend. For demonstration purposes an additional OpenID Connect/OAuth 2 user authorization is included in the REST backend.

User Flow / Program Flow

• User logs in into the system
• The UI is loading the available machines and displays them
• The user can select one of the available machines for further details
• Afterwards the machine visualization (in our sample SVG) and some machine specific data (settings, switches) is loaded and displayed
• The used can directly interact with settings and switches in the displayed machine visualization

Technologies

The following technologies should be demonstrated:

• OAuth 2, OpenID Connect, JWT, ASP.NET JWT Middleware
• ASP.NET (Web API) and the Open API Specification (Swagger)
• gRPC, ASP.NET gRPC
• .NET in Docker/K8s
• SignalR
• TypeScript

Project architecture

Overall project folder structure

The following (sub-)projects are part of this sample:

• ASP .NET project with API controllers and REST service endpoints
• gRPC machine simulation as remote machine data service
• HTML5 web frontend as simple 2D HMI frontend

Notes

Project is built with GitHub Actions.
