Already on GitHub? Sign in to your account we would like to generate a file on the fly on the file system Path.GetTempFileName(), then return PhysicalFile(filePath) in the action controller and delete the file right after to avoid filling up the disk.
We created a custom Result to delete the file after it has been executed, look like it's working, but is this approach correct ?

public class PhysicalFileDeleteFileResult : PhysicalFileResult
public override async Task ExecuteResultAsync(ActionContext context)
await base.ExecuteResultAsync(context);
File.Delete(FileName);
