Project Dependency Tree

Explore complete .NET project-to-project dependencies from a Visual Studio Solution as a clean, recursive tree.

Overview

Project Dependency Tree is a Visual Studio Code extension for understanding project-to-project dependencies across an entire .sln or .slnx solution.

It focuses only on project dependencies. It does not turn the solution into a file, folder, class, namespace, or package graph.

Highlights

Supports .sln and .slnx solutions.
Discovers projects across nested .slnx folders.
Builds a recursive dependency tree from ProjectReference relationships.
Shows all solution projects in a searchable project list.
Highlights a selected project and its upstream dependents.
Shows direct and indirect relations for the selected project.
Supports expand/collapse, previous/next occurrence navigation, and cycle detection.
Works with project types such as .csproj, .fsproj, .vbproj, and .sqlproj.
Exports the complete dependency tree to a TXT file.
Requires no additional VS Code extension or third-party runtime dependency.

Supported dependency model

The extension uses ProjectReference entries as the dependency source.

Web.Api
└── Application
    └── Domain

In this example, Application is a direct dependency of Web.Api, while Domain is an indirect dependency.

Only projects declared by the selected Solution are included in the dependency model. References to projects outside that Solution are not added to the tree.

Export

Use Export TXT in the dependency-tree header to save the current tree as a UTF-8 text file.

The extension opens the standard Save dialog and suggests a filename based on the selected Solution.

Installation

From the Marketplace

Search for Project Dependency Tree in the VS Code Extensions view and select Install.

From a VSIX

For local installation:

code --install-extension project-dependency-tree-0.15.0.vsix

Usage

Open the Command Palette with Ctrl+Shift+P.
Run Project Dependency Tree: Open.
Select a .sln or .slnx file.
Select a project from the project list or dependency tree.
Explore its dependency relationships.

Commands

Command	Description
`Project Dependency Tree: Open`	Select a Solution and open the dependency view.
`Project Dependency Tree: Export Tree to Text`	Export the dependency tree to a TXT file.

Requirements

Visual Studio Code 1.90.0 or later.
A .sln or .slnx solution containing the projects you want to inspect.

Privacy

The extension reads the selected Solution and project files locally to build the dependency model. It does not send project contents to a remote service.

Development

The extension is implemented with the VS Code Extension API, Webview HTML/CSS/JavaScript, and bundled Codicon assets. It has no runtime dependency on a third-party tree or graph library.
