Thanks, it is recognized, But now shows me an CreateSemaphore error at 
Open() method.

This is a sample of my code

string conn = "Server=localhost;Database=siscontrol;Data 
Source=localhost;Port=3306;User Id=root;Password=passwd123";
MySql.Data.MySqlClient.MySqlConnection db = new 
db.Open(); <--- ERROR HERE

The error message is

*Server error in '/' Application


*Description: *Error processing request.

*Error Message: *HTTP 500. System.EntryPointNotFoundException: 

*Stack Trace: *

System.EntryPointNotFoundException: CreateSemaphore
  at (wrapper managed-to-native) MySql.Data.Common.Semaphore:CreateSemaphore (MySql.Data.Common.SECURITY_ATTRIBUTES&,int,int,string)
  at MySql.Data.Common.Semaphore..ctor (Int32 initialCount, Int32 maximumCount) [0x00000] 
  at (wrapper remoting-invoke-with-check) MySql.Data.Common.Semaphore:.ctor (int,int)
  at MySql.Data.MySqlClient.MySqlPool..ctor (MySql.Data.MySqlClient.MySqlConnectionString settings) [0x00000] 
  at MySql.Data.MySqlClient.MySqlPoolManager.GetPool (MySql.Data.MySqlClient.MySqlConnectionString settings) [0x00000] 
  at MySql.Data.MySqlClient.MySqlConnection.Open () [0x00000] 

I'm using the connector/net In a previous version of mono the 
code above works fine with my connection string.

Any help or hint.

Best regards
