An entry has been added to the 6.0.8, 6.1.6, 6.2.5, 6.3.6 changelogs: MySQL Connector/NET for .NET/Mono attempted to dynamically load the assembly Mono.Posix.dll when a Unix socket was used to connect to the server. This failed and the connector was not able to use a Unix socket unless the Mono.Posix.dll assembly was previously loaded by the program.
Description: The 2.6.4 connector download for .NET/Mono tries to dynamically load the Mono.Posix.dll assembly when a unix socket is used to connect to the server. This fails and the connector cannot use a unix socket unless the Mono.Posix.dll assembly is previously loaded by the program. How to repeat: Compile the following program in linux with gmcs (Mono's C# compiler) and run it: ----------------------------------------------- using System; using MySql.Data.MySqlClient; namespace test { class MainClass { public static void Main (string[] args) { string connString = "Server=/var/run/mysqld/mysqld.sock; Database=INSERT_SCHEMA_HERE; User ID=INSERT_USERNAME_HERE; Password=INSERT_PASSWORD_HERE; Protocol=unix;"; MySqlDataReader reader = MySqlHelper.ExecuteReader(connString, "SHOW TABLES"); while (reader.Read()) { Console.WriteLine(reader[0]); } } } } ------------------------ Expected result: the output of SHOW TABLES Actual results: System.IO.FileNotFoundException: Could not load file or assembly 'Mono.Posix' or one of its dependencies. The system cannot find the file specified. Suggested fix: The problem is that the connector is using something like: Assembly x = Assembly.Load ("Mono.Posix"); which fails (Assembly.LoadWithPartialName () would work, but is obsoleted), instead of: Assembly x = Assembly.Load ("Mono.Posix, Version=2.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756"); Note: "Mono.Posix, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756" and "Mono.Posix, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756" would also work just fine.
