The Npgsql Development team is proud to announce that Npgsql 2.2.0 beta1 is now available!
This release has the following highlights:
Visual Studio DDEX support
Kenji Uno added support for DDEX. Now you can use Npgsql with Visual Studio data designer. This is a missing feature a lot of our users requested in the past. Kenji added a tutorial about how to use Npgsql with DDEX. You can find it here.
Support for EFMigration and Database creation in EF6+David Karlaš added support for that. Now it is possible to start Code First projects without needing to create a database upfront. EntityFramework and Npgsql will take care of it.
Emil Lenngren added support for a lot of missing features of EntityFramework.
Check out this list containing fixes from David and Emil as well as others for EntityFramework.
In this release, SSLStream is on by default.
If you want to use Mono.Security, you will need to use the following line in your code:
NpgsqlConnection.UseSslStream = false;
Note that in future releases, this option may not be available anymore as we are removing the dependency on Mono.Security assembly. Let us know in the forums if you have any problem with ssl when using SSLStream. This will help us check if we will be able to remove Mono.Security assembly.
Added support for JSON, JSONB and HSTORE datatypes
Shay added support for those datatypes.
Added GSSAPI support on Windows
Brian Crowell added support for GSSAPI on windows. Now it is easier to use Active Directory when authenticating users.
Removed support for protocol v2
Postgresql versions which use only protocol 2 are very old and don't receive support from postgresql group anymore. By removing support for protocol version 2, we removed a lot of code and can focus on functionalities provided by protocol 3.
Removed support for Postgresql 8.3 and below
In this thread, we talked about making Npgsql support the officially supported postgresql versions. Postgresql has a table of officially supported versions and we decided to follow this table to guide us which postgresql version we will have support to.
This doesn't necessarily mean that Npgsql won't work on unsupported versions. It may work if we don't add any SQL or unsupported feature. For example, today Npgsql 2.2 works only on Postgresql 8.2 and above because we added server side support for command timeout handling and some other queries which aren't supported on earlier versions.
Complete release notes for this release can be found on our github release page.

With the merge of Pull Request #213 (PR #213), Kenji Uno added support for Visual Studio Design Time also known as DDEX.
A most wanted feature
From the statistics of pageviews I get from a previous post about design time support, I can affirm that this is a most wanted feature of Npgsql. And I'm very glad to say that Npgsql is finally having it. I'd like to thank Kenji Uno for all his hard work to make this happen.
Npgsql DDEX support is done through an extension file which can be easily installed in Visual Studio. This is a much better situation than we had before where it was needed to use an experimental instance of Visual Studio.
The code started with wwindcloud in PR #67 and Kenji started to play with it and said he was working to get it usable in VS2012 and 2013.
Some time later, Kenji said he had some success to get Npgsql DDEX initially working and started to fix the bugs he was finding.
In order to be able to add more fixes to the code, Kenji started the PR 213 and started to add more features and fixes until now when we merged all the changes back to master branch.
How to use it
Kenji Uno wrote a tutorial about how to build and use this feature. Below are some screenshots from the tutorial.
Please, give it a try and let us know if it works for you. Remember that this is a work in progress, so you may face bugs and problems.
I'd like to thank Kenji Uno for all his hard work to get this feature working. And also thank wwindcloud for the initial work.
Here is an screenshot when you double click the .vsix file to install the extension:
When you install it, you will be able to select it when creating a new data source connection:

Npgsql 2.1.2 is out!
This is a bug fix release. Two fixes are present:
This is a bug fix release. Two fixes are present:
- KeyNotFoundException when setting ApplicationName on NpgsqlConnectionStringBuilder and
- A regression when using NHibernate with queries containing '<' operator. (Less Than' prepare failing). Unfortunately, this fix breaks previous support for @@ operators. So if you need this support, you will have to use the previous 2.1.1 version. Glen Parker is working in a permanent fix. Sorry for this big inconvenience. More info about that can be found at the link above.
Please, give it a try and let me know if you have any problems. Please, report your issues in our github issues page.
