  InnerException:

your app config should look like this:

<configuration>
    <connectionStrings>
        <add name="dbTorontoTrader" connectionString="server=localhost;database=dbtorontotrader;user id=root; password=password" providerName="MySql.Data.MySqlClient"/>
     </connectionStrings>
</configuration>

Make note of the element that is missing

You need to add connectionstrings element.

Your app.config should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="dbTorontoTrader"
         connectionString="server=localhost;database=dbtorontotrader;user id=root; password=password"
         providerName="MySql.Data.MySqlClient"/>
  </connectionStrings>
</configuration>
