Today we released the first beta of Npgsql 2.0.13!  This new beta release had a lot of bugs fixed and initial support for Entity Framework 6! More information about how to use Entity framework 6 with Npgsql can be found in  this post . Checkout the release notes for more information about the bugs fixed in this release. Download it from our  downloads section . Important notice about this release Unfortunately, I made a mistake when updating the assembly version for this release and it was created with a wrong value. I'm very sorry for that. This release should have been 2.0. 12 .91 and not 2.0. 13 .91 Next beta release will have the version value fixed. What are the implications?  The biggest problem is that this beta version will have a version number higher than the final 2.0.13 version while this beta version has 2.0.13.91. As it is a beta and it is not supposed to be deployed in production systems, we think this won't give problems to o

Recently,  I applied a patch from  Kevin Pullin  which will improve the performance of programs using Npgsql. This patch reduces significantly the time to create new NpgsqlConnection objects. This particularly applies in scenarios where you are creating and disposing a lot of NpgsqlConnection objects, like when  you are using connection pool , ( you are using it, right? :) ). Comparison test I made an artificial test to show the impact of this patch. This test consists of a simple loop where I create 10k NpgsqlConnection objects.  class   Program     {          static   void   Main ( string []  args )         {              var   connString   =   "server=127.0.0.1;userid=npgsql_tests;database=npgsql_tests;" ;                                       Stopwatch   sw   =   Stopwatch . StartNew ();                                       for  ( int   i   =   0 ;  i   <   10000 ;  i ++ )             {                  var   conn   =   new   NpgsqlConnection ( connStri

In my last post , I said there is a pull request by Pēteris Ņikiforovs to add support for EF-6 to Npgsql. Yesterday, I merged this pull request to the master branch of Npgsql . With this merge, Npgsql has officially initial support for EF-6! How to compile For now, in order to compile Npgsql to use EF-6, you have to open the solution file NpgsqlEF6.sln. Later,  as suggested by Pēteris Ņikiforovs , the idea is that we create a new configuration inside main project solution instead of maintain 2 separated projects. Another thing you will need to compile Npgsql is the latest release of EntityFramework assembly through NuGet: PM> Install-Package EntityFramework -Pre That's it! Now you will be able to play with Npgsql and EF-6. Check out my previous post about how to use Npgsql with EntityFramework. I'd like to thank Pēteris Ņikiforovs for his patch. And maxbundchen for his patch about Open/Close events needed for EF-6. Please, give it a try and let me know how it

After reading the excellent article about entity framework on Postgresql by Brice Lambson, I decided to write this post to document my experience playing with Entity Framework 4.3.1 and Npgsql. This post will be an adaptation of the Code First To a New Database walkthrough in order to make it work with Npgsql.  First Steps You should follow the first 4 steps of Code First To a New Database. Go ahead, I''l wait for you. Next steps Here is where the adaptation of the walkthrough begins. As Brice noted in his post, Npgsql currently doesn't support database creation. ( I'm working on that and hope to get news about it soon.) So, for while, you have to create the database manually. Those are the steps you have to do to create the database and the model: First, run this command in the terminal to create the database (or you can use pgAdmin if you prefer a GUI): > createdb ef_code_first_sample  After that, you have to run the following commands
