[Question][Need Help] Using for existing entity

[hitaspdotnet]

Hi,
Is there any documents about using Geocoding.Net for existing Address entity?
I have a already complete Project as School Research and my teacher asked for adding component for getting GeoLocation by user address's.
But the existing Address Entity isn't just a string.

    [Table("Addresses")]
    public class Address 
    {
		public virtual string FirstName { get; set; }

		public virtual string LastName { get; set; }
		
		public virtual string Email { get; set; }
		
		public virtual string Company { get; set; }

		public virtual string Address1 { get; set; }
		
		public virtual string Address2 { get; set; }

		public virtual string ZipPostalCode { get; set; }

		public virtual string PhoneNumber { get; set; }
		
		public virtual string FaxNumber { get; set; }

		public virtual long CountryId { get; set; }
		public Country Country { get; set; }
		
		public virtual long StateOrProvinceId { get; set; }
		public StateOrProvince StateOrProvince { get; set; }
		
		public virtual long CityId { get; set; }
		public City City { get; set; }
		
		public virtual long? DistrictId { get; set; }
		public District District { get; set; }
    }

Please! Can anyone guide me to do this?
