Minimum sample FS in C#

[SuperJMN]

Hello!

I'm a .NET user wanting to create a new filesystem implementation. I've installed the latest vertsion of WinFsp in my Windows 11 and and I've created a sample C# project. Everything seems ready to go. It's a console project where I installed the nuget package (winfsp.net" version 2.0.23075) .

As I said, I'd like to create an implementation for SeaweedFS, but I'm a bit lost with the data required by WinFsp.
It would really be of help if .NET developers like me had a minimum filesystem that only return a fixed list of hardcode files.

My current implementation is this:

public class SeaweedFS : FileSystemBase
{
    public override int GetSecurityByName(string FileName, [UnscopedRef] out uint FileAttributes, ref byte[] SecurityDescriptor)
    {
        FileAttributes = (UInt32)System.IO.FileAttributes.Normal;
        return STATUS_SUCCESS;
    }

    public override int Open(string FileName, uint CreateOptions, uint GrantedAccess, [UnscopedRef] out object FileNode, [UnscopedRef] out object FileDesc, [UnscopedRef] out FileInfo FileInfo, [UnscopedRef] out string NormalizedName)
    {
        FileInfo = new FileInfo()
        {
            FileSize = 12,
            CreationTime = 4,
            FileAttributes = 2,
        };

        NormalizedName = FileName;
        FileNode = new MyNode();
        FileDesc = default(object);

        return STATUS_SUCCESS;
    }

    public override void Close(object FileNode, object FileDesc)
    {
        base.Close(FileNode, FileDesc);
    }

    public override int ReadDirectory(object FileNode, object FileDesc, string Pattern, string Marker, IntPtr Buffer, uint Length, [UnscopedRef] out uint BytesTransferred)
    {
        BytesTransferred = 0;
        return STATUS_SUCCESS;
    }
}

Of course, it doesn't work.
So, what do I need to make it work? I'd be happy in the Windows Explorer showed a bunch of fake files / dirs.

Thanks a lot and congratulations for your WONDERFUL work.

There are multiple sample .NET file systems here. Easiest to start with may be passthrough-dotnet.
