roslyn Analyze source code with Roslyn Analyze a simple "Hello World" application in VB.NET

Example

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

Remember the path to the .vbproj 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 projectPath = "C:\HelloWorldApplication\HelloWorldProject.vbproj"

' Creating a build workspace.
Dim workspace = MSBuildWorkspace.Create()

' Opening the Hello World project.
Dim project = workspace.OpenProjectAsync(projectPath).Result

' Getting the compilation.
Dim compilation = project.GetCompilationAsync().Result

For Each tree In compilation.SyntaxTrees

    Console.WriteLine(tree.FilePath)

    Dim rootSyntaxNode = tree.GetRootAsync().Result

    For Each node In rootSyntaxNode.DescendantNodes()

        Console.WriteLine($" *** {node.Kind()}")
        Console.WriteLine($"     {node}")
    Next
Next

Console.ReadKey()

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