是否有Akka.net持久性与MongoDb在那里的工作示例？

Question

我正在尝试用日志持久性配置Akka.Net到MongoDb，但它引发了一个我无法弄清楚的异常。 有没有一个参考例子可以在任何地方看到，看看它应该如何工作？我会期望在单元测试中的例子来填补我的这个需求，但是对于MongoDb持久性实现缺少测试。 :(

下面是我收到的错误：

Akka.Actor.ActorInitializationException : Exception during creation ---> 
System.TypeLoadException : Method 'ReplayMessagesAsync' in type 
'Akka.Persistence.MongoDb.Journal.MongoDbJournal' from assembly 
'Akka.Persistence.MongoDb, Version=1.0.5.2, Culture=neutral, PublicKeyToken=null' 
does not have an implementation. 

这里是我为这个应用程序HOCON： ---编辑 - 谢谢你的提示Horusiath;基于我更新到这个HOCON和SQLite的提供者的作品，但MongoDB的一个仍然给了一个错误

所以，回到我原来的问题：是否有正在MongoDB的样品，我可以检查以了解这是怎么意工作？

配置要求为程序集提供完全限定的类型名称。尝试指定类为"Akka.Persistence.MongoDb.Journal.MongoDbJournal, Akka.Persistence.MongoDb"（您可能不需要双引号，因为它不是内联字符串）。
