C# - Unexpected authentication method mysql_native_password exception

问题

I didn't see anything on this, but I've been trying for the longest time to get some practice with an SQL database. I tried MSSQL and was frustrated to no end, so I tried MySQL and got a bit further. The database seems to be up and running, and I even did a query to make a table. Although when trying to connect with Microsoft's C# Express edition I get the exception: "unexpected authentication method mysql_native_password" I know the password is correct. I'm even referencing MySQL.Data.dll. Here's my code, I get the exception on connection.Open().Can someone please help me out?

     public Form1()
     {
      MySqlConnection connection = new MySqlConnection("Data Source = localhost;          Initial Catalog = MySQL55; Integrated Security = SSPI; User ID = root; Password = <REMOVED>;");

        try
        {
            connection.Open();
        }

        finally
        {
            if (connection != null)
            {
                connection.Close();
            }
        }
     }

What provider are you using? If you are using MySQL Connecter .net, then you connection string should be something like...

Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;

If you are using eInfoDesigns provider, then...

Data Source=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;Command Logging=false;

If SevenObjects

Host=myServerAddress;UserName=myUsername;Password=myPassword;Database=myDataBase;

if Devart

User ID=root;Password=myPassword;Host=localhost;Port=3306;Database=myDataBase; Direct=true;Protocol=TCP;Compress=false;Pooling=true;Min Pool Size=0;Max Pool Size=100;Connection Lifetime=0;

if MySQLDriverCS

Location=myServerAddress;Data Source=myDataBase;User ID=myUsername;Password=myPassword;Port=3306;Extended Properties="""";

if MySql OLEDB

Provider=MySQLProv;Data Source=mydb;User Id=myUsername;Password=myPassword;

if .Net OLEDB

Provider=MySQLProv;Data Source=mydb;User Id=myUsername;Password=myPassword;

if MySQl Connector

Driver={MySQL ODBC 5.5 Driver};Server=localhost;Database=myDataBase; User=myUsername;Password=myPassword;Option=3;

It is actually much easier to use SQL Server as it is built in and VS is designed to work with it.
