我有一个问题。我在 Visual Studio 中创建了一个数据实体模型。在 Linq 中;

Guid RtuDataId = db.RtuData.Where(x => x.CommunicationUnit.Id == new Guid(ID))
.OrderByDescending(x => x.ReadOn)
.LastOrDefault().Id;

我收到错误;

does not recognize the method ... method, and this method cannot be translated into a store expression.

我在 Google 中搜索过,但我不明白这个错误。
