✅ How to handle websockets?

I have this handler. I wanna save all active connections to list, is it worth it?

public sealed class UserConnectionHandler : IDisposable
{
    public required string SessionId { get; init; }

    public required string ConnectionId { get; init; }
    
    public WebSocket? Socket { get; set; }

    public DateTime? LastActivityDateTime { get; set; }

    public async Task SendEventAsync(string message, CancellationToken cancellationToken)
    {
        if(Socket?.State == WebSocketState.Open)
        {
            var buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(message));
            await Socket.SendAsync(buffer, WebSocketMessageType.Text, true, cancellationToken).ConfigureAwait(false);
        }
    }

    public async Task CloseAsync(WebSocketCloseStatus closeStatus, CancellationToken cancellationToken)
    {
        if(Socket?.State == WebSocketState.Open)
        {
            await Socket.CloseAsync(closeStatus, string.Empty, cancellationToken).ConfigureAwait(false);
        }
    }

    public void Dispose()
    {
        Socket?.Dispose();
    }

public sealed class UserConnectionHandler : IDisposable
{
    public required string SessionId { get; init; }

    public required string ConnectionId { get; init; }
    
    public WebSocket? Socket { get; set; }

    public DateTime? LastActivityDateTime { get; set; }

    public async Task SendEventAsync(string message, CancellationToken cancellationToken)
    {
        if(Socket?.State == WebSocketState.Open)
        {
            var buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(message));
            await Socket.SendAsync(buffer, WebSocketMessageType.Text, true, cancellationToken).ConfigureAwait(false);
        }
    }

    public async Task CloseAsync(WebSocketCloseStatus closeStatus, CancellationToken cancellationToken)
    {
        if(Socket?.State == WebSocketState.Open)
        {
            await Socket.CloseAsync(closeStatus, string.Empty, cancellationToken).ConfigureAwait(false);
        }
    }

    public void Dispose()
    {
        Socket?.Dispose();
    }

I don't know, whether it is worth it depends on whether you need it, I suppose Any reason you're not using Signalr?

It will be good to use signalr but I cant. Web client doesnt want to use signalr library to communicate with backend Client wants websockets

I would like to store this connections in list. Connection can be disposed so the main question: is it safe to save idisposable connections to list?
