C# driver version 1.4.1 released

[Robert Stam]

Version 1.4.1 of the C# driver is now available.

This is a minor release intended to fix a few issues found in the first iteration of support for LINQ.

Note: the LINQ implementation has only been tested with C#. We plan to add unit tests for VB.NET as soon as possible.

The release notes are available online at:

https://github.com/mongodb/mongo-csharp-driver/blob/master/Release%20Notes/Release%20Notes%20v1.4.1.md

The C# driver is available for download in source or binary form (.msi installer or .zip file) from:

http://github.com/mongodb/mongo-csharp-driver

http://github.com/mongodb/mongo-csharp-driver/downloads

Note: if you download the zip file, depending on how you unzip the file you may need to "Unblock" the help file. You can do so by right clicking on the "CSharpDriverDocs.chm" file and selecting Properties, and then clicking on the "Unblock" button. You will need to "Unblock" the help file if you see the message "Navigation to webpage was canceled" where the help text would normally appear.

The C# driver will also be available soon on NuGet at:

http://www.nuget.org/List/Packages/mongocsharpdriver

Online documentation is available at:

http://www.mongodb.org/display/DOCS/CSharp+Language+Center

The online API reference documentation is available at:

http://api.mongodb.org/csharp/

Note: the online and API reference documentation will be updated to v1.4.1 over the next several days.

Bugs and suggestions can be submitted at:

We monitor this group and will be happy to answer any questions you post here.

We have fixed the two issues raised by Roman Kuzmin. The related JIRA tickets are:

https://jira.mongodb.org/browse/CSHARP-446

https://jira.mongodb.org/browse/CSHARP-447

The issue with SetDocumentId caught us by surprise because we thought of SetDocumentId as an internal method. However, because the interface that defines SetDocumentId was not implemented privately it leaked out to the public API of the BsonDocument class. In the next point release we are temporarily changing the behavior of SetDocumentId back to match 1.4.0 and earlier for backward compatibility reasons, but at the same time we are marking these methods as obsolete and intend to make them private in a later release. The usual way of setting the _id field of a BsonDocument is:

    document["_id"] = value;

The issue with Query.In only occurs if you cast a BsonArray to IEnumerable<BsonValue> before calling Query.In, so there's a good chance you won't be affected by that either. See the JIRA ticket CSHARP-447 for sample code affected by this issue.

Even though both issues appear to be relatively minor and might not affect too many users, the probability of more users being affected is high enough that we are planning a 1.4.2 release in the coming week. Both known issues are currently fixed, and we simply want to wait a few more days to make sure there are no other minor issues that would be worth addressing in the 1.4.2 point release.

Thanks for the feedback, and please let us know if you have any other issues or questions.

Roman, have you filed this in the C# driver project?

Also, there is a bug.

 

\Driver\Builders\QueryBuilder.cs(1015):

public QueryConditionList In(IEnumerable<BsonValue> values)

 

It calls `if (values.Contains(null)) ...` with a null argument. At the same time in

 

\Bson\ObjectModel\BsonArray.cs(648):

public bool Contains(BsonValue value)

 

.. there is:

            if (value == null)

            {

                throw new ArgumentNullException("value");

            }

 

Thus, `In` seems to be always throwing an exception.
