DependsOn

Here's a sample preview where we are checking MAUI's Core project and then the entirety of the MAUI sln file.

A C# Class Dependency Visualizer

A tool that scans your C# solution or project file and generates a dependency graph of classes, including base class hierarchies and class references.
Built using Roslyn for code analysis.

Features

• Solution-wide analysis — Scans all projects and documents in a .sln file.
• Single project support — Can directly scan a .csproj file without requiring a full solution.
• Base class tracing — Shows class inheritance paths all the way up to the root base class.
• Reference mapping — Shows which classes reference other classes.
• Filter by root node — Focus on a specific class and its related dependencies.
• Cross-project support — Works even if classes span multiple projects in the solution.

Usage

From the command line:

DependsOn <path-to-sln-or-csproj> /f|/r|/i

Options:

/f - Scan both Reference and Inheritance links
/r - Scan Reference links only
/i - Scan Inheritance links only

Examples:

DependsOn MySolution.sln /f
DependsOn MyProject.csproj /i

Output

• The generated JSON file will be saved in the same folder as the DependsOn executable.
• The file name will be:

  <SolutionOrProjectFileName>.dependency-graph.json
  

  For example:

  MySolution.sln.dependency-graph.json
  MyProject.csproj.dependency-graph.json
  

Viewing the Graph

1. Run the DependsOn tool to generate the JSON file.
2. Go to https://dependson.vercel.app/.
3. Upload the generated .dependency-graph.json file.
4. Explore the dependency graph interactively.
