Default struct with default value [Answered]

I have this struct

public readonly struct RuntimeConfiguration
{
    public int MaxLineCount { get; init; } = 10_000;



    public RuntimeConfiguration()
    {
    }
}

public readonly struct RuntimeConfiguration
{
    public int MaxLineCount { get; init; } = 10_000;



    public RuntimeConfiguration()
    {
    }
}

I also have a method which takes a parameter

RuntimeConfiguration configuration = default

RuntimeConfiguration configuration = default

, yet this default instance does not have

MaxLineCount

MaxLineCount

set to the value 10000? Does

default

default

only initialize the struct with every field to its type's default value, and not any user-provided default value?
