Well Antiaaa, you have 1 of 2 choices to resolve this issue
1) define a class named RegistrationInformation
2) define a struct named RegistrationInformation
you cant have both either in the same namespace or defined with each other.
Code:
public struct RegistrationInformation
{
public string FirstName { get; set; }
.
.
.
}
or
Code:
public class RegistrationInformation
{
public string FirstName { get; set; }
.
.
.
}
