Answer: If you are using Asp.Net 6 or Asp.Net 5 add Encoding.RegisterProvider(CodePagesEncodingProvier.Instance) in the Startup.cs after installing System.Text.Encoding and System.Text.Encoding.Pages in the Main Application (Do not install these libraries in other In project class library project otherwise it won't work).
