In Code Block 1, you can see I am using these classes to connect to the AdventureWorks database and executing a SELECT statement against it. Apart from these two important classes there are a couple of other classes as well, some of them I will be demonstrating in these examples. To execute a command you would create an instance of the SqlCommand class, assign appropriate properties and execute the command on the connection you created. You can create a factory which signalR will used to generate an access token on each.
