SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you create clear, visual representations of your .NET application's architecture, flows, and data models, making complex systems easier to understand and communicate.

Core Features & Use Cases

  • Architecture Diagrams: Generate C4-style context, container, and component diagrams, as well as layered and microservice topology views.
  • Sequence Diagrams: Illustrate API request flows, async patterns, and middleware pipelines.
  • Class & ER Diagrams: Visualize domain models, DI graphs, and database schemas.
  • State & Flowcharts: Map out workflows, state machines, and decision trees.
  • Use Case: Quickly generate a C4 container diagram for your new ASP.NET Core microservice to share with your team during a design review.

Quick Start

Generate a C4-style context diagram for a .NET application.

Frequently Asked Questions about dotnet-mermaid-diagrams

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a Mermaid diagram for a .NET project architecture?▼

You can generate Mermaid diagrams for .NET projects by using a tool that adheres to Mermaid v10+ and .NET 8.0+ conventions, producing diagram-as-code for architecture, sequence, class, and ER visualizations.

What is a C4 model diagram and how is it used in .NET applications?▼

C4 model diagrams visualize software architecture across context, container, and component levels, helping map layered topologies and microservice structures within .NET applications for clearer team communication.

Can I visualize API request flows and middleware pipelines as sequence diagrams?▼

Yes, sequence diagrams can illustrate API request flows, async patterns, and middleware pipelines, mapping the interactions and processes across your application architecture.

Does this approach work with domain models and database schemas?▼

Yes, class and ER diagrams support visualizing domain models, dependency injection graphs, and database schemas, mapping structural relationships and entity workflows effectively.

What is the best way to map state machines and workflows in a .NET application?▼

State diagrams and flowcharts map out workflows, state machines, and decision trees, providing diagram-as-code visualization that aligns with .NET 8.0+ conventions.

Do I need specific tools to create deployment and flowchart diagrams for microservices?▼

You need a generator supporting Mermaid v10+ and .NET 8.0+ conventions to create deployment diagrams, microservice topologies, and flowcharts without manual drawing tools.
