public struct StructTest() // no warning
{
    public string Text { get; set; }
}

public struct StructTest2
{
    public string Text { get; set; }
    public StructTest2() { } // warning CS8618: Non-nullable property 'Text' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.
