roslyn Analyze source code with Roslyn Analyze a simple "Hello World" application in C#

Example

Create a new console application with one line in the Main method: Console.WriteLine("Hello World")

Remember the path to the .csproj file and replace it in the example.

Create a new Console Application and install the Microsoft.CodeAnalysis NuGet package and try the following code:

const string projectPath = @"C:\HelloWorldApplication\HelloWorldProject.csproj";

// Creating a build workspace.
var workspace = MSBuildWorkspace.Create();
        
// Opening the Hello World project.
var project = workspace.OpenProjectAsync(projectPath).Result;

// Getting the compilation.
var compilation = project.GetCompilationAsync().Result;

foreach (var tree in compilation.SyntaxTrees)
{
    Console.WriteLine(tree.FilePath);

    var rootSyntaxNode = tree.GetRootAsync().Result;

    foreach (var node in rootSyntaxNode.DescendantNodes())
    {
        Console.WriteLine($" *** {node.Kind()}");
        Console.WriteLine($"     {node}");
    }
}

Console.ReadKey();

This will print all the files and all the syntax nodes in your Hello World project.
