What's this syntax in this object instantiation

This screenshot is straight from MimeKit's quick start guide here: https://mimekit.net/docs/html/Creating-Messages.htm I understand body is being declared as a new object of type TextPart. The constructor is being passed the string "plain", but next to that: that bracketed block, what's the C# structure/syntax being used here? How is that Text variable assignment in the block being associated to the body object? I'd like to look it up but I'm not sure what to go reading about. Can I have some super beginner help? 🙂

REPL Result: Success

class Foo

    public int Bar { get; set; }
}

var f = new Foo {
    Bar = 69
};

f.Bar

class Foo
{
    public int Bar { get; set; }
}

var f = new Foo {
    Bar = 69
};

f.Bar

Result: int

It basically compiles down to

var f = new Foo();
f.Bar = 69;

var f = new Foo();
f.Bar = 69;

As a side note, if you use a raw string literal (or whatever the triple-quoted string is called) you can have this large string indented better:

message.Body = new TextPart("plain") {
    Text = """
        Hey Alice,
        
        What are you up to...
        """
};

message.Body = new TextPart("plain") {
    Text = """
        Hey Alice,
        
        What are you up to...
        """
};
