MassTransit is a program that runs as a service on your computer. When you install it, two services will be added to your Services Control Panel – MassTransit Engine and MassTransit Transporter. The default startup type of the services is Automatic and that is why they start automatically when you log into your computer. However, you need to start them manually the first time you start MassTransit after the installation.
To administer MassTransit, you need the MassTransit Administrator application. By default, it is being installed on your computer along with the MassTransit services (if you have not unselected it during the installation process). To load MassTransit Administrator, you have to start the MassTransit services first.
