C # - create custom SQL table type using SQLCommand Fails

I am trying to create a database on the fly for my unit testing script.

Using SQL Server LocalDB 11.00.3000 .NET 4.0

I can create / drop a database and add SPs, Views, Tables, etc ... everything is fine using a straight SQL script.

The problem occurs when I try to create a custom TYPE.

CREATE TYPE test as TABLE( [Action_Item_Id] INT,[Shift_Id] NVARCHAR (34))

.... works fine in the SQL console. But in the code ....

SqlConnection conn = new SqlConnection(connString);
conn.Open();
var cmd = new SqlCommand("CREATE DATABASE UnitTestingDatabase",conn);
conn.ChangeDatabase("master");
cmd.ExecuteNonQuery();
conn.ChangeDatabase("UnitTestingDatabase");
cmd.CommandText = "CREATE TYPE test as TABLE( [Action_Item_Id] INT,[Shift_Id] NVARCHAR (34))";
cmd.ExecuteNonQuery();

I am getting an exception:
