## NetworkHelper usage

`NetworkHelper` provides two patterns for establishing a network connection: a blocking token-based approach for simple use-cases, and an event-based approach for background connection management.

### Token-based (retryable)

Call `SetupAndConnectNetwork` with a `CancellationToken` timeout. This method can be called repeatedly — if the first attempt times out, call it again:

```csharp
bool connected = false;
while (!connected)
{
    CancellationTokenSource cs = new(30000);
    connected = NetworkHelper.SetupAndConnectNetwork(requiresDateTime: true, token: cs.Token);
    if (!connected)
    {
        Debug.WriteLine($"Network not ready, status: {NetworkHelper.Status}");
        // wait before retrying
        Thread.Sleep(5000);
    }
}
```

### Event-based

Call `SetupNetworkHelper` once at startup. The helper connects in the background. Wait on `NetworkReady`:

```csharp
NetworkHelper.SetupNetworkHelper(requiresDateTime: true);

if (!NetworkHelper.NetworkReady.WaitOne(30000, true))
{
    Debug.WriteLine($"Failed to connect: {NetworkHelper.Status}");
}
```

> **Note:** `NetworkReady` is reset when the connection is lost and re-signaled when it is restored, accurately reflecting live network state. Code that previously assumed `NetworkReady` would remain set after first connect should be updated to handle transient disconnects.

### Reset and reconfigure

Call `Reset()` to fully reset the helper so it can be called again with different settings, or to restart after an error:

```csharp
NetworkHelper.Reset();

// Now call SetupNetworkHelper or SetupAndConnectNetwork again
NetworkHelper.SetupNetworkHelper(requiresDateTime: true);
```

`SetupNetworkHelper` throws `InvalidOperationException` if called a second time without a prior `Reset()`. Token-based methods (`SetupAndConnectNetwork`) do not have this restriction and are always retryable.
