Entity Framework ORM
The FileManager widget allows you to manage file system items that use the Entity Framework ORM to link to a database. You can use the Remote File System Provider to connect to the file system on the client side. To process the widget's HTTP requests on the server, create your own file system provider, which implements the IFileSystemItemLoader and IFileSystemItemEditor interfaces.
Feel free to share demo-related thoughts here.
