Do some work after the response in ASP.NET Core

Question

I have an ASP.NET Core website, using EFCore. I would like to do some work like logging to the database, but after having sent the response to the user in order to answer faster

Answer 1

Building on Jeans answer and a question and answer on the try - return - finally pattern, the try and finally blocks can be removed (if you don't really want to catch an exception).

This leeds to the following code:

public async Task Request([FromForm]RequestViewModel model, string returnUrl = null)
{
    var newModel = new ResponseViewModel(model);

    // Some work 

    Response.OnCompleted(async () =>
    {
        // Do some work here
        await Log(model);
    });

    return View("RequestView",newModel);
}
