vb.net 2010: Can't connect to a MySQL DB (64 bit) under Windows 10

Hi there, I'm trying to write a vb.net program (VS 2010) that connects to a MySQL DB (64 bit) under Windows (10).

Amongst other attempts these are my recent once:

 Dim MyConString As String = "DRIVER={MySQL ODBC 5.3 Unicode Driver};" & _ "SERVER=localhost;" & _ "DATABASE=CitraTest;" & _ "UID=xxxx;" & _ "PASSWORD=xxxx;" & _ "OPTION=3;" 

' -------------------------------------------------------------------------------------------

 Dim MyConString As String = "Provider=MSDASQL;" & _ "DRIVER={MySQL ODBC 5.3 Unicode Driver};" & _ "SERVER=127.0.0.1;" & _ "PORT=3306;" & _ "DATABASE=CitraTest;" & _ "UID=xxxx;" & _ "PASSWORD=xxxx;" & _ "OPTION=3;" 

' -------------------------------------------------------------------------------------------

 Dim MyConString As String = "DSN=CitraTest;" & _ "SERVER=127.0.0.1;" & _ "DATABASE=CitraTest;" & _ "UID=xxxx;" & _ "PASSWORD=xxxx;" 'Connection Dim MyConnection As New System.Data.Odbc.OdbcConnection(MyConString) MyConnection.Open() 

The error message is always the same:

 Dim MyConnection As New MySql.Data.MySqlClient.MySqlConnection Dim myConnectionString As String myConnectionString = "server=127.0.0.1;" _ & "uid=xxx;" _ & "pwd=xxx;" _ & "database=CitraTest;" MyConnection.ConnectionString = myConnectionString MyConnection.Open()
