Can't get SocketManager to work properly

public class TestClient : ConnectionManager
{
	public override void OnConnecting(ConnectionInfo info)
	{
		Debug.Log("Connecting");
	}

	public override void OnConnected(ConnectionInfo info)
	{
		Debug.Log("Connected");

		string str = "Msg for Server";
		Connection.SendMessage(Marshal.StringToHGlobalUni(str), str.Length * 2 + 1, SendType.Reliable);
	}

	public override void OnDisconnected(ConnectionInfo info)
	{
		Debug.Log("Disconnected");
	}

	public override void OnMessage(IntPtr data, int size, long messageNum, long recvTime, int channel)
	{
		Debug.Log("Msg received: " + Marshal.PtrToStringUni(data));
	}
}

public class TestServer : SocketManager
{
	public override void OnConnecting(Connection connection, ConnectionInfo data)
	{
		connection.Accept();
		Debug.Log($"{data.Identity} is connecting");
	}

	public override void OnConnected(Connection connection, ConnectionInfo data)
	{
		Debug.Log($"{data.Identity} has joined the game");

		string str = "Msg for client";
		connection.SendMessage(Marshal.StringToHGlobalUni(str), str.Length * 2 + 1, SendType.Reliable);
	}

	public override void OnDisconnected(Connection connection, ConnectionInfo data)
	{
		Debug.Log($"{data.Identity} has disconnected");
	}

	public override void OnMessage(Connection connection, NetIdentity identity, IntPtr data, int size, long messageNum, long recvTime, int channel)
	{
		Debug.Log($"We got a message from {identity}!");

		connection.SendMessage(data, size, SendType.Reliable);
	}
}

public class Test : MonoBehaviour
{
	TestServer server;
	TestClient client;

	private void Awake()
	{
		SteamManager.Initialize();

		server = SteamNetworkingSockets.CreateNormalSocket<TestServer>(NetAddress.AnyIp(12345));
		client = SteamNetworkingSockets.ConnectNormal<TestClient>(NetAddress.LocalHost(12345));
	}

	private void Update()
	{
		server.Receive();
		client.Receive();
	}
}

Output in Unity: Connecting ip:[::1]:56920 is connecting ip:[::1]:56920 has joined the game Connected Msg received: Msg for client⤀뚿졚솄嬄ﾠᑄ젪ꗜ訛좘쯱⠶תּ⿩姏㉉鿀흆ɔ

Problem: For some reason the message to the server never triggers the OnMessage method in the TestServer class. Most of the time there are random characters after the message I receive.

@WilhelmW got a fix! See #467

You need to pump messages with Receive() otherwise OnMessage will not be called.
