C# MySql Connector/Net issues
Currently running Mono. I loaded MySQL and installed connector/net in my gac folder located in /usr/lib/mono/gac. The problem is that everytime I try to run it using a simple connection test, I get the following error:
** (/home/holland/Code/csharp/test/Test/bin/Debug/Test.exe:10278): WARNING **: The following assembly referenced from /home/holland/Code/csharp/test/Test/bin/Debug/Test.exe could not be loaded:

It should be an assembly file if I recall correctly
Here's my code:
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using MySql.Data.MySqlClient;
namespace Test
{
public class Database
{
public Database()
{
}
public static IDbConnection MainConnect()
{
string connectionInfo =
"Server=localhost;"+
"Database=ecom_main;"+
"User ID=root;"+
"Password=xxxxxxx"+
"Pooling=false;";
return new MySqlConnection(connectionInfo);
}
using System;
using System.Data;
using MySql.Data.MySqlClient;
namespace Test
{
class MainClass
{
public static void Main (string[] args)
{
IDbConnection dbMain = Database.MainConnect();
Console.WriteLine(dbMain);
}
}
}
I had the same problem and I solved it following this steps:
- Make a copy case sesitive of the dll:
#cp mysql.data.dll MySql.Data.dll
- Install the connector
#gacutil -i -package 2.0 MySql.Data.dll
This installs in the GAC and also adds a symlink in /usr/lib/mono/2.0 - If the assembly does not appear in monodevelop, then you can add a reference to the dll in the project to /usr/lib/mono/2.0
