SLNX is a fast parser and writer for the (currently) new in-preview Visual Studio XML Solution format with a .slnx extension, introduced in Visual Studio 2022 17.10 Preview 3.

Available on NuGet: https://nuget.org/packages/Slnx

Reading

using Slnx;

var model = SlnxModel.Load(File.ReadAllText("TestSlnx.txt"));

foreach (Folder folder in model.TopLevelFolders!)
{
    foreach (string file in folder.DescendantFiles!)
    {
        Console.WriteLine(file);
    }
}

TestSlnx.txt content:

<Solution>
    <Folder Name="Solution Items">
        <File Path="File1.cs" />
        <File Path=".editorconfig" />
        <Project Path="File.csproj" />
        <Folder Name="Test">
            <File Path=".editorconfig" />
            <File Path="data.cs" />
        </Folder>
    </Folder>
</Solution>

Output:

File1.cs
.editorconfig

Writing

using Slnx;

var factory = new SlnxFactory();
factory.Folders.Add(new Folder("Solution Items", new[]
{
    new Project("./CSharp/CSharp.csproj"),
    new Project("./VB.NET/VB.NET.vbproj"),
    new Project("./DockerCompose/DockerCompose.dcproj", Guid.NewGuid(), new(solution: "*|*", project: "*|*|Deploy"))
}, new[]
{
    new Folder("C++", Array.Empty<Project>(), Array.Empty<Folder>(), new[]
    {
        "util.cpp",
        "util.h",
        "data.cc",
        "data.h"
    })
}, new string[] { "File1.cs", "File2.cs" }));

factory.Projects.Add(new Project("Slnx/Slnx.csproj"));
factory.Projects.Add(new Project("App/App.shproj"));

var model = factory.AsModel();
model.Store("OutputSlnx.txt");
