Async initialization in an ApiController

Question

Does ApiController have an extension point/override that can be used to Initialize async resources?

I want to have something like this:

public ValuesController : ApiController
{
    private IFoo _foo;
    protected async override void InitializeAsync(HttpControllerContext controllerContext)
    {
        _foo = await CreateFooAsync();
    }
}

I know I can do this in each controller action but I would like to avoid having to do it in 4/5 different actions.

You can override core controller method: ExecuteAsync. Like this:

public override async Task<HttpResponseMessage> ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken) {
    _foo = await CreateFooAsync();
    return await base.ExecuteAsync(controllerContext, cancellationToken);
}
