ProjGraph.Lib.ClassDiagram

Roslyn-powered class hierarchy analysis and Mermaid class diagram generation for .NET projects.

NuGet License: MIT

Installation

dotnet add package ProjGraph.Lib.ClassDiagram

Overview

ProjGraph.Lib.ClassDiagram uses the Roslyn workspace API to analyze C# source code and generate Mermaid class diagrams. It supports:

  • Analyzing individual .cs files or entire project workspaces
  • Extracting classes, records, interfaces, abstract types, enums, and structs
  • Capturing fields, properties, methods, and their visibility modifiers
  • Detecting inheritance, implementation, and composition relationships
  • Configurable member visibility filters

Usage

Register all services:

using ProjGraph.Lib.Core;
using ProjGraph.Lib.ClassDiagram;

services.AddProjGraphCore();
services.AddProjGraphClassDiagram();

Generate a class diagram from a project

using ProjGraph.Lib.ClassDiagram.Application;
using ProjGraph.Lib.ClassDiagram.Application.UseCases;

var analysisService = provider.GetRequiredService<IClassAnalysisService>();

var result = await analysisService.AnalyzeAsync("src/MyProject/MyProject.csproj", new AnalysisOptions
{
    IncludePrivateMembers = false,
    IncludeInternalTypes = false
});

var renderer = provider.GetRequiredService<MermaidClassDiagramRenderer>();
string diagram = renderer.Render(result);

Example output:

classDiagram
    class OrderService {
        +PlaceOrder(request OrderRequest) Task~Order~
        +CancelOrder(id Guid) Task
    }
    class IOrderRepository {
        <<interface>>
        +FindById(id Guid) Task~Order~
    }
    OrderService --> IOrderRepository

Analyze a single file or directory

var analyzeFile = provider.GetRequiredService<AnalyzeFileUseCase>();
var result = await analyzeFile.ExecuteAsync("src/Domain/Order.cs");

var analyzeDirectory = provider.GetRequiredService<AnalyzeDirectoryUseCase>();
var result = await analyzeDirectory.ExecuteAsync("src/Domain/");

Key Services
