protobuf-net 能否处理新的自动只读属性，即使用单个 get 定义的自动属性，而不使用 private set？
public class WithReadonlyProperty {
public int ReadonlyProperty { get; }
public WithReadonlyProperty(int val) {
ReadonlyProperty = val;
}
}
当我这样做的时候
RuntimeTypeModel
.Default
.Add(typeof (WithReadonlyProperty), false)
.Add(nameof(WithReadonlyProperty.ReadonlyProperty));
var test = new WithReadonlyProperty(12345);
using (var output = File.Create(@"c:\temp\_readonly.bin")) {
try {
Serializer.Serialize(output, test);
} catch (Exception e) {
Console.WriteLine(e);
}
}
我得到这个异常:
System.InvalidOperationException: Cannot apply changes to property WithReadonlyProperty.ReadonlyProperty

是否可以将 protobuf-net 配置为使用公共(public)构造函数？也许还有其他方法可以做到吗？如果可能，我想避免使用属性装饰 WithReadonlyProperty 类。
