✅ Finding all FieldInfo's of BackingFields of a type
I have following code snippet to find all FieldInfo's of a type t which are BackingFields of public properties of type double. 
FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();
FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();
I was now wondering if the CompilerGeneratedAttribute is only applied to BackingFields or if there are other instances of fields having that attribute since I cannot currently think of any. If it is only applied to BackingFields, I could skip the step of getting all properties.
