I am going back and adding some functionality to an existing ASP web app. I need to do some form-based uploading of files. I don't have my references with me but I think this will be fairly simple ...

Take advantage of the IFormFile interface in ASP.Net Core MVC to upload small files, large files, and multiple files ...

File Providers in ASP.Net Core provide a layer of abstraction on the file system, allowing us to easily obtain file and directory information, watch for changes, and of course access physical files.
