AscendingGuidGenerator.cs |
|||
new Guid generator that generates Guids that are ascending according to MongoDB |
|||
(the Guids will only be ascending if stored using GuidRepresentation.Standard) |
|||
|
|||
CombGuidGenerator.cs |
|||
this class is not deprecated, but the Guids it generates are only ascending if compared the weird way SQL Server compares Guids |
|||
timestamp portion now uses SQL server timer resolution (1/300th of a second per tick) |
|||
|
|||
InterfaceSerializer.cs |
|||
new serializer that can be used with any interface |
|||
Deserialize uses a discriminator convention to figure out the actual type and calls Deserialize on the actual type's serializer |
|||
Serialize looks up the serializer of the actual type and calls Serialize on the actual type's serializer |

BsonClassMap.cs |
|||
renamed private method ResolveExplicitProperty to FindPropertyImplementation and made it more robust |
|||
|

GetSerializer now returns an InterfaceSerializer if the type is an interface |

C# Driver Version 1.8.1 Release Notes |
|||
===================================== |
|||
C#/.NET Driver Version 1.8.1 Release Notes |
|||
========================================== |
|||
|
|||
This is a minor release. It should be considered a mandatory upgrade from 1.8. The |
|||
issues fixed were minor changes but their impact is not minor. In particular, if |
|||
you are using replica sets or are using InsertBatch with very large batches you |
|||
should consider 1.8.1 a mandatory upgrade. |
|||

BSON Library Changes |
|||
==================== |
|||
|
|||
Handling of closed sockets |
|||
-------------------------- |
|||
|
|||
There was an unfortunate regression in 1.8 with respect to sockets closed by the |
|||
server which causes the driver to hang waiting for data that is never going to |
|||
arrive. |
|||
|
|||
This was discovered by a user who called Shutdown (which of course resulted in |
|||
all sockets being closed), but you could also encounter this issue if |
|||
you are connecting to replica sets and the primary closes all sockets when it |
|||
steps down (either due to an explicit step down or a re-election). |
|||
|
|||
AscendingGuidGenerator |
|||
---------------------- |
|||
|
|||
If you are using Guids as your _ids and you want the values to be ascending so |
|||
that they are always inserted at the right hand side of the index you can use |
|||
this IdGenerator. Note that for the server to see the Guids as ascending you |
|||
have to make sure to store them in the right representation, which is |
|||
GuidRepresentation.Standard. |
|||
|
|||
We used to recommend CombGuidGenerator for this use case, but we have since |
|||
realized that the Guids generated by the CombGuid are only considered ascending |
|||
when Guids are compared using SQL Server's method of comparing Guids. |
|||
|
|||
Driver Changes |
|||
============== |
|||
|
|||
MongoCollection |
|||
--------------- |
|||
|
|||
There is a new overload of Distinct which returns the values as TValue(s) |
|||
instead of as BsonValue(s). |
|||
|
|||
There was a bug in InsertBatch that resulted in a high probability of |
|||
InsertBatch failing if the batch was big enough to have to be split into |
|||
multiple sub-batches. |
|||
|
|||
MongoDatabase |
|||
------------- |
|||
|
|||
RunCommandAs now uses the standard serialization mechanisms to deserialize |
|||
all command results returned from the server. |
