Using TPL with existing async APIs

I want to use TPL with a existing API, RestSharp to be specific, so I can use continuations.

But this means I have to wrap a API that doesn't take the classical .NET approach to async, but instead implements callbacks. Take some code like this:

var client = new RestClient("service-url");
var request = new RestRequest();

client.ExecuteAsync<List<LiveTileWeatherResponse>>(request, 
    (response) =>
    {
        ...
    });

So here I want to wrap the ExecuteAsync in TPL, if it's possible. But I can't for the life of me, figure out how to do it.

Any ideas?
