MongoDB 错误be UuidLegacy, not UuidStandard

错误：The GuidRepresentation for the reader is CSharpLegacy, which requires the binary sub type to be UuidLegacy, not UuidStandard

三种解决方案：

1、修改全局配置 BsonDefaults.GuidRepresentation

　　在MongoDB初始化的地方加上：BsonDefaults.GuidRepresentation = GuidRepresentation.Standard;

　　

 2、当你创建collection时指定配置

　　MongoDatabase db = ???;
　　string collectionName = ???;
　　var collectionSettings = new MongoCollectionSettings {
　　　　GuidRepresentation = GuidRepresentation.Standard
　　};
　　var collection = db.GetCollection<BsonDocument>(collectionName, collectionSettings);

3、更新驱动

　　MongoDB.Driver 、MongoDB.Driver.Core 、MongoDB.Bson 统统更新至2.7.0版本

亲测方案1、3有效
