Cannot get MySQL assembly to load in powershell - mysql

Question

I cannot get a connection to a linux mysql container running ubuntu on my local machine. I'm using powershell to create a mysql connection. Brand new to working with databases and putting in data so really no idea what I'm doing.
In the container, I've created a DB
mysql> CREATE DATABASE mydb;
Query OK, 1 row affected (0.04 sec)
mysql> CREATE TABLE test (id INT, text varchar(50), date_val date, date_time datetime);
mysql> USE mydb;
Database changed
mysql> CREATE TABLE test (id INT, text varchar(50), date_val date, date_time datetime);
Query OK, 0 rows affected (0.12 sec)
Testing the connection to the port the container was configured for from my local host
PS C:\Users\me> Test-NetConnection 127.0.0.1 -Port 3306
ComputerName : 127.0.0.1
RemoteAddress : 127.0.0.1
RemotePort : 3306
InterfaceAlias : Loopback Pseudo-Interface 1
SourceAddress : 127.0.0.1
TcpTestSucceeded : True
Here's my powershell script
[void][System.Reflection.Assembly]::LoadWithPartialName("MySql.Data")
$constr = "server=127.0.0.1:3306;port=3306;database=mydb;user id=root;password=P#ssw0rd"
$con = New-Object MySql.Data.MySqlclient.MySqlConnection
$con.ConnectionString = $constr
$con.Open()
$cmd = New-Object MySql.Data.MySqlClient.MySqlCommand
$cmd.CommandText = "INSERT INTO test VALUES(#id, #text, #date, #datetime)"
$cmd.Connection = $con
$cmd.Prepare()
$today = get-date
$cmd.Parameters("#id").Value = 1
$cmd.Parameters("#text").Value = "Text Value"
$cmd.Parameters("#date").Value = $today
$cmd.Parameters("#datetime").Value = $today
$cmd.ExecuteNonQuery()
$con.close()
This is the error that I get

Answer 1

it was my syntax. This worked (although I still get this error...the table populates)
