TL;DR

Pre-Dotnet Core 3.0 uses the format below to map incoming json properties to C# model properties

1
2
3
4
5
6

public class Model
{
    [JsonProperty("first_name")]
    public string FirstName

}

Dotnet Core 3.x now uses

1
2
3
4
5
6

public class Model
{
    [JsonPropertyName("first_name")]
    public string FirstName

}

Attempting to use the first version in a Dotnet Core 3.x Application will fail to bind and those properties will be null.

This is a follow up from the article on Casting Custom Types To C# Built-In Types.

In the previous article we looked at how we would take a custom object like a Class or a Struct and cast it to a C# built-in like a bool. In this article we will look at how to cast from one custom type to another.

What we will be exploring here is much like what AutoMapper does.

bool variableName = Convert.ToBoolean(c1);

//1. variableName is false
//2. runtime exception
//3. It depends
