InvalidOperationException - No reading operation to complete

If I send 2 messages in a row from the client, the serer got an InvalidOperationException (No reading operation to complete).

Here is my clients Send-Click-Event Code that I have changed - see 2nd call to SendMessageAsync:

private async void Button_Click_1(object sender, RoutedEventArgs e)
{
	if (_chatConnection == null)
	{
		Log.Text += "No connection!\n";
	}
	else
	{
		await _chatConnection.SendMessageAsync(new ChatMessage(chatMessageTextBox.Text));
		// this is my additional SendMessageAsync call
		await _chatConnection.SendMessageAsync(new ChatMessage(chatMessageTextBox.Text));
		Log.Text += $"Sent message: {chatMessageTextBox.Text}\n";
	}
}

The server exception is raised in ProcessSocketMainLoop.

Any hints on this?
