I am trying to verify phone number using PhoneNumbers.dll(File version 8.9.0.0) for twillio SMS API with C# (Visual studio 2010)

Lines of Code used in application:

private static PhoneNumberUtil phoneUtil = PhoneNumberUtil.GetInstance();
private static List<string> supportedRegions = phoneUtil.GetSupportedRegions().ToList<string>();

After application build, facing below error

The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

enter image description here

In case same dll used in .Net 2015 no error results with build successed. Please suggest to over come system.object error in .net 2010

Im not sure why .net standard is not working for you

however if you really need to you can go to an early version of libphonenumber-csharp

https://www.nuget.org/packages/libphonenumber-csharp/7.7.4

  • please share me the link to download net standard 2 supported for visual studio 2010 – Pavankumar Apr 12 '18 at 12:13
  • @Pavankumar the nuget package i linked you to, that particular version 7.7.4 doesn't require .net standard, you don't need it with that version – TheGeneral Apr 12 '18 at 12:16
  • Thank you for the responses and suggestions I have used phonenumbers.dll version 3.7.1.306 and used below link to for my understanding https://stackoverflow.com/questions/31611446/how-to-format-a-phone-numbers-with-libphonenumber-in-international-format var phoneUtil = PhoneNumberUtil.GetInstance(); var numberProto = phoneUtil.Parse("1234567890", "IT"); var formattedPhone = phoneUtil.Format(numberProto, PhoneNumberFormat.INTERNATIONAL); – Pavankumar Apr 18 '18 at 07:21
  • @Pavankumar you shouldn't need to go back to version 3. 7.7.4 seems like it would work, anyway im glad you got it working – TheGeneral Apr 18 '18 at 07:24
