NamedPipeServer.cs

Before

public static NamedPipeServerStream CreatePipe(string pipeName, PipeSecurity pipeSecurity)
{
    return new NamedPipeServerStream(pipeName, PipeDirection.InOut, 1, PipeTransmissionMode.Byte, PipeOptions.Asynchronous | PipeOptions.WriteThrough, 0, 0, pipeSecurity);
}

After

public static NamedPipeServerStream CreatePipe(string pipeName, PipeSecurity pipeSecurity)
{
    var stream = new NamedPipeServerStream(pipeName, PipeDirection.InOut, 1, PipeTransmissionMode.Byte, PipeOptions.Asynchronous | PipeOptions.WriteThrough, 0, 0);
    if (pipeSecurity is not null) stream.SetAccessControl(pipeSecurity); //Windows Only
    return stream;
}

PipeStreamWriter.cs

Before

private readonly BinaryFormatter _binaryFormatter = new BinaryFormatter();

try
{
    using (var memoryStream = new MemoryStream())
    {
        _binaryFormatter.Serialize(memoryStream, obj);
        return memoryStream.ToArray();
    }
}

After

try
{
    var byteArray = JsonSerializer.SerializeToUtf8Bytes(obj, Globals.JsonOptions);
    return byteArray;
}

PipeStreamReader.cs

Before

private readonly BinaryFormatter _binaryFormatter = new BinaryFormatter();

using (var memoryStream = new MemoryStream(data))
{
    return (T) _binaryFormatter.Deserialize(memoryStream);
}

After

using (var memoryStream = new MemoryStream(data))
{
    var obj = JsonSerializer.Deserialize<T>(memoryStream, Globals.JsonOptions);
    return obj;
}    

Globals.cs

Add Globals

namespace NamedPipeWrapper
{
    public static class Globals
    {
        public static readonly JsonSerializerOptions JsonOptions = new()
        {
            ReferenceHandler = ReferenceHandler.Preserve,  //cyclical references OK
        };
    }
}
