How to call the async method in a method that returns Task?

Question

In a SignalR hub, I have this:

public class MyHub : Hub
{
    public override Task OnConnected()
    {
        // my async code here
        return base.OnConnected();
    }
}

I want to execute asynchronous code. So I added the keyword asyncas follows:

public class MyHub : Hub
{
    public override async Task OnConnected()
    {
        var result = await MyAsyncMethod();
        return base.OnConnected();
    }
}

but return base.OnConnected();shows this error:

Since MyHub.OnConnected () is an async method that returns Task, a Returned keyword should not be accompanied by an expression of the object. Did you intend to return Task<T>?

How can i fix this? thank.

async . return, Task , Task .

await base:

public override async Task OnConnected()
{
    var result = await MyAsyncMethod();
    await base.OnConnected();
}
