ImageResizer.ImageBuilder giving error of Could not load type 'System.Web.Hosting.HostingEnvironment' .Net core MVC 6

Question

I am trying to resizing my image if its extension is among .jpg, .jpeg, .png or .webp. below is my code

if (System.IO.Path.GetExtension(newFileName).ToLower() == ".jpg" || System.IO.Path.GetExtension(newFileName).ToLower() == ".png" || System.IO.Path.GetExtension(newFileName).ToLower() == ".jpeg" || System.IO.Path.GetExtension(newFileName).ToLower() == ".webp")
                {
                    var path = Path.Combine(_webHostEnvironment.WebRootPath, CMSUserAreaDir, "content_media/raw/" + newFileName);
                    var image = new ImageResizer.ImageJob(file, path, new ImageResizer.Instructions("maxwidth=1920"), false, false);
                    string a = ImageResizer.ImageBuilder.Current.Build(image).FinalPath;
                }

and I'm getting this error Anyone please help me to know what I'm doing wrong. Thanks in advance.

I am not sure if I am missing any packages in my setup for this to happen, or I am not supposed to use ImageJob in this manner.

When I'm looking at packages for ImageResizer its shows message like this

above issue is resolved. note that ImageResizer is not compatible with .net 6 yet, maybe it will in future. Till then there are many alternatives available, I've used SixLabors.Imagesharp to resolved my issue. here is updated code :

var path = Path.Combine(_webHostEnvironment.WebRootPath, CMSUserAreaDir, "content_media/raw/" + newFileName);
                //var image = new ImageResizer.ImageJob(file, path, new ImageResizer.Instructions("maxwidth=1920"), false, false);
                //string a = ImageResizer.ImageBuilder.Current.Build(image).FinalPath;
                using (var image = Image.Load(file.OpenReadStream()))
                {
                    if (image.Width > 1920)
                    {
                        image.Mutate(x => x.Resize(new ResizeOptions
                        {
                            Size = new Size(1920, 0),
                            Mode = ResizeMode.Max
                        }));
                    }

                    image.Save(path);
                }

you need to add these packages:

<PackageReference Include="SixLabors.ImageSharp" Version="3.0.0" />
