ProjGraph

.NET tool ecosystem for visualizing project dependencies, database schemas, and class hierarchies.

# Install
dotnet tool install -g ProjGraph.Cli

# Visualize project dependencies
projgraph visualize ./MySolution.slnx

# Generate Entity Relationship Diagram (from DbContext or ModelSnapshot)
projgraph erd ./Data/MyDbContext.cs

# Generate Class Diagram for a class and its hierarchy
projgraph classdiagram ./Models/User.cs

# Compute key solution metrics (project counts, depth, hotspots)
projgraph stats ./MySolution.slnx

  "servers": {
    "ProjGraph.Mcp": {
      "type": "stdio",
      "command": "dnx",
      "args": ["ProjGraph.Mcp@x.x.x", "--yes"]
    }
  }
}

# CLI
dotnet run --project src/ProjGraph.Cli -- visualize ./ProjGraph.slnx

# Stats
dotnet run --project src/ProjGraph.Cli -- stats ./ProjGraph.slnx

# MCP Server
dotnet run --project src/ProjGraph.Mcp

# Mermaid format (default)
projgraph visualize ./MySolution.sln

# ASCII tree format
projgraph visualize ./MySolution.sln --format tree

# Mermaid format for documentation
projgraph visualize ./MySolution.slnx --format mermaid --output docs/dependencies.mmd

# Generate ERD from DbContext
projgraph erd ./Data/MyDbContext.cs

# Generate ERD from ModelSnapshot (leveraging migrations)
projgraph erd ./Migrations/MyDbContextModelSnapshot.cs

# Output to Markdown for documentation
projgraph erd ./Data/MyDbContext.cs --output docs/database-schema.md

# Control how EF Core owned types (OwnsOne/OwnsMany) are rendered:
# 'mirror' (default) inlines a table-split owned type onto its owner as EF names it;
# 'classic' gives every owned type its own entity box regardless of table mapping
projgraph erd ./Data/MyDbContext.cs --owned-mode classic

# Generate diagram for a class and its inheritance and dependencies
projgraph classdiagram ./Models/Admin.cs -i -d

# Control discovery depth (default: 1)
projgraph classdiagram ./Models/Admin.cs -i -d --depth 5

# Display project counts, depth stats, and hotspot projects
projgraph stats ./MySolution.slnx

# Show top 10 most-referenced projects
projgraph stats ./MySolution.slnx --top 10

You: "Analyze the dependencies in my solution"
AI: [Generate the architecture diagram]

You: "Generate a class diagram for the User class"
AI: [Generates the class hierarchy]

You: "Show me the entity relationships in my DbContext"
AI: [Generates the database schema]

You: "Give me a health summary of my solution"
AI: [Returns project counts, depth stats, and hotspot projects]
