Deserialization fails/misses readonly collection properties

[perpetualKid]

below sample code fails since deserializer does not restore the collection items, even if collections are initialized.
Making the "Collection" property writable { get; set; } would solve that, but raises CA2227 warnings.

When restoring/deserializing collection properties, code could check if collections are alreay initialized, and add the restore items to the existing collection, instead of trying to set the collection property itself value.Collection = __Collection;

If it's not intended to handle readonly collection properties, code analysis warning or runtime error should be raised, and also the properties should be exempted from serizalization.

        public Collection<string> Collection { get; } = new Collection<string>();
    }

    internal class Program
    {
        static async Task Main(string[] args)
        {
            CollectionTest sourceCollection = new CollectionTest();
            sourceCollection.Collection.Add("1234");
            sourceCollection.Collection.Add("5678");

            Pipe bufferPipe = new Pipe();
            MemoryPackSerializer.Serialize(bufferPipe.Writer, sourceCollection);
            _ = await bufferPipe.Writer.FlushAsync().ConfigureAwait(false);
            ReadResult resultBuffer = await bufferPipe.Reader.ReadAsync().ConfigureAwait(false);

            CollectionTest resultCollection = MemoryPackSerializer.Deserialize<CollectionTest>(resultBuffer.Buffer);
            Debug.Assert(resultCollection.Collection.Count == 2);
        }
    }
