Before MTS can host an in-process component in its process space, it needs to have a package created. The package, which can easily be created in the MTS Explorer, is a collection of components that run in the same process. Creating packages is the final step in the development process. Package developers and advanced system and Web administrators use the MTS Explorer to create and deploy packages. You use the Explorer to implement the package and component configuration that is determined during development of the application.
Packages define the boundaries for a server process running on a server computer.
For example, if you group a sales component and a purchasing component in two different packages, these two components will run in separate processes with process isolation. A big advantage of using MTS packages is that you can specify a package identity, and all the components contained in the same package will use that identity when accessing and launching its components. After compiling and registering the component on the local machine, we need to create an empty package to host the remote component within the MTS Explorer. In the left pane of MTS Explorer, select the computer for which you want to create a package. Open the Packages Installed folder for that computer.
