Question

We are working with .NET Core Web Api, and looking for a lightweight solution to log requests with variable intensity into database, but don\'t want client\'s to wait for th

Answer 1

The original HostingEnvironment.QueueBackgroundWorkItem was a one-liner and very convenient to use. The "new" way of doing this in ASP Core 2.x requires reading pages of cryptic documentation and writing considerable amount of code.

To avoid this you can use the following alternative method

    public static ConcurrentBag bs = new ConcurrentBag();

    [HttpPost("/save")]
    public async Task SaveAsync(dynamic postData)
    {

    var id = (String)postData.id;

    Task.Run(() =>
                {
                    bs.Add(Create(id));
                });

     return new OkResult();

    }


    private Boolean Create(String id)
    {
      /// do work
      return true;
    }

The static ConcurrentBag bs will hold a reference to the object, this will prevent garbage collector from collecting the task after the controller returns.
