SolutionDependencyAnalyzer

There are two ways to use the tool: Command line or use the NuGet package in your project.

Command Line

dotnet tool install --global dependency-analyzer

dependency-analyzer <SolutionFullPath> <OutputPath>

-g or --create-graph-image : runs dot at the end of the process to create a png image of the dot graph generated. This option has a prerequisite: dot must be installed and in the PATH. To do so, you can run this command for Chocolatey: choco install graphviz or get dot there.

This tool will create five files in the provided OutputPath:

packages.md contains the list of NuGet packages used by the projects in the solution, with their version.
packagesByProject.md will list the NuGet packages used by each project in the solution, with their version.
projectsByPackage.md does the opposite: it will list the projects that use each package
projectDependencyGraph.dot is the dependency graph of the projects in the solution. SolutionDependencyAnalyzer also generates a png of that graph, projectDependencyGraph.png

Create a DependencyAnalyzer and call it, with Solution containing the full solution path:

var dependencyAnalyzer = new DependencyAnalyzer(Solution);
await dependencyAnalyzer.AnalyzeAsync();

Now dependencyAnalyzer properties contain everything you need:

PackageResults contains the package ID as key, and its version as value
ProjectResults is a dictionary in which the key is a project, and the values are its project dependencies
PackagesByProject is a dictionary in which the key is a project, and the values are its package dependencies
ProjectsByPackage is a dictionary in which the key is a package, and the values are its project dependencies

You can also call the writers (MarkdownWriter and DotWriter) if you want to write the same fils as the comand line tool does.

This project was heavily inspired by dotnet-depends, and like dotnet-depends, it uses the amazing Buildalyzer
