Examples

This example shows how to display the current application's target framework and run-time dependencies:

Console.WriteLine($"Target framework: {DependencyContext.Default.Target.Framework}");
Console.WriteLine();
Console.WriteLine("Runtime libraries:");
Console.WriteLine();

foreach (RuntimeLibrary lib in DependencyContext.Default.RuntimeLibraries)
{
    if (lib.Dependencies.Count > 0)
    {
        Console.WriteLine($"{lib.Name} depends on: ");

        foreach (Dependency dep in lib.Dependencies)
        {
            Console.WriteLine($"- {dep.Name}, Version {dep.Version}");
        }
    }
    else
    {
        Console.WriteLine($"{lib.Name} does not have dependencies");
    }

    Console.WriteLine();
}

Remarks

When a .NET application is compiled, the SDK generates a JSON manifest file (<ApplicationName>.deps.json) that contains information about application dependencies. You can use the DependencyContext class to read information from this manifest at run time.
