Serialization in .NET Core is the process of converting the state of an object into a format that can be stored or transmitted. The serialized form can then be deserialized back into an object of the same type.

In .NET Core, there are two main serialization frameworks:

• The System.Text.Json framework, which is the default serialization framework in .NET Core. It is a high-performance, low-memory-allocation framework that supports JSON serialization and deserialization.
• The System.Runtime.Serialization framework, which is a more mature framework that supports a wider range of serialization formats, including XML, binary, and custom formats.

To serialize an object in .NET Core, you can use the following steps:

1. Create a serializer.
2. Serialize the object to a string or stream.

The following code shows how to serialize an object to a string using the System.Text.Json framework:

C#

using System.Text.Json;

public class Person {
    public string Name { get; set; }
    public int Age { get; set; }
}

var person = new Person { Name = "John Doe", Age = 30 };

var serializer = new JsonSerializer();
var json = serializer.Serialize(person);

The json variable will now contain the serialized representation of the person object.

To deserialize an object from a serialized form, you can use the following steps:

1. Create a deserializer.
2. Deserialize the object from a string or stream.

The following code shows how to deserialize an object from a string using the System.Text.Json framework:

C#

using System.Text.Json;

public class Person {
    public string Name { get; set; }
    public int Age { get; set; }
}

var json = "{\"Name\":\"John Doe\",\"Age\":30}";

var serializer = new JsonSerializer();
var person = serializer.Deserialize<Person>(json);

The person variable will now contain the deserialized object.
