OpenTl 自动更新电报消息会引发错误 CS0079 c#

Question

I recently tried to use the auto update example that is on the OpenTL quick start page, and just using the following basic example

await clientApi.UpdatesService.AutoReceiveUpdates += update =>
{
// Handle updates
 switch (update)
    {
        case TUpdates updates:
            break;
        case TUpdatesCombined updatesCombined:
            break;
        case TUpdateShort updateShort:
            break;
        case TUpdateShortChatMessage updateShortChatMessage:
            break;
        case TUpdateShortMessage updateShortMessage:
            break;
        case TUpdateShortSentMessage updateShortSentMessage:
            break;
        case TUpdatesTooLong updatesTooLong:
            break;
    }
};

It won't compile throwing this error :

Error CS0079 The event 'IUpdatesService.AutoReceiveUpdates' can only appear to the left of += or -=

I put it into an async Task function, but I don't think thats the problem. I don't really know how to use an async event like that. link to the example

The way you have written it is wrong. It rather should be

clientApi.UpdatesService.AutoReceiveUpdates += async update => 
{
// Handle updates
 switch (update)
    {
