     static baseUrl: string = 'http://localhost:52949/V1/';
          static baseImageUrl: string = 'http://localhost:52949/';
          static baseClientUrl: string = 'http://localhost:58082/'

        static baseUrl: string = 'http://98.142.86.22/EMSDEMOAPI/V1/';
        static resetPasswordlinkUrl: string = 'http://98.142.86.22/EMS/#/Resetpassword';

How to maintain two classes under same namespace like partial class in c#. Its giving error if we have same class name in typescript as duplicate identifier.

Can anyone know how to resolve this issue ?
