Generation Data Matrix in Visual C#.NET Creating Dependencies

Often, an application has dependencies . For example, application A is dependent on application B if you must install application B before installing application A . MDT 2010 allows you to specify application dependencies for each application you add to the deployment share . You can make an application dependent only on other applications that you ve added to the deployment share . To add dependencies to an application, perform the following steps:

1. 2. 3.

In the Deployment Workbench console tree, click Applications . In the details pane, right-click the application that has a dependency on another application and then click Properties . On the Dependencies tab, shown on the following page, do the following:

To add an application to the dependencies list, click Add, select an application, and then click OK . Deployment Workbench only displays applications in this list that you ve already added to the deployment share . To remove an application from the dependencies list, select an application in the dependencies list and then click Remove .

To reorder the applications in the dependencies list, select an application in the dependencies list and then click Up or click Down . MDT 2010 installs the dependent applications in the order specified by the dependencies list .

In MDT 2010, the task sequence specifies the tasks that run during deployment and their order . You can install applications during the imaging process by adding a step to the task sequence that installs the application at the appropriate time . For more information about customizing the task sequence, see 6 . Although this approach is useful for injecting applications into a disk image, using the MDT 2010 database or CustomSettings .ini is more appropriate during deployment in production . For more information, see 12, Deploying with Microsoft Deployment Toolkit . Without creating additional groups in the task sequence, the best place to add application installs is to the Custom Tasks group, which MDT 2010 creates in each task sequence s default task sequence . The instructions in this section show you how to install an application as a step under this group .

sequence, the Windows Deployment Wizard will allow the user to install the application optionally during deployment. also, you can choose applications to install automatically during a Zero Touch Installation by configuring the deployment share to install the application automatically.

To add an application installation to a task sequence, perform the following steps:

In the Deployment Workbench console tree, click Task Sequences, which is located under Deployment Share . In MDT 2010, you must create a deployment share before adding applications to it . For more information about creating deployment shares, see 6 . In the details pane, right-click the task sequence in which you want to install an application and then click Properties . On the Task Sequence tab, shown here, click Custom Tasks in the task sequence and then click Add, click General, and then click Install Application .

2. 3.

Click the Install Application task that you just added to the task sequence, select the Install A Single Application option, click Browse, choose an application, and then click OK, as shown here .

In MDT 2010, the task sequence is very flexible. For example, you can install appli-

cations at almost any point during the State Restore phase. You can filter application installation tasks on a variety of variables. For more information about editing task sequences in MDT 2010, see 6.

Summary

Careful planning is the most important task you must undertake when deploying applications with Windows 7 . The first step is building an application inventory . Then you must prioritize, categorize, and document the installation of each application . MDT 2010 and ACT provide tools that help with this step . Another key planning step is determining the right type of deployment strategy for your organization . Thick images are monolithic images that contain core applications and other files . They are large and costly to maintain and deploy . Thin images are bare images . You install applications post-deployment using a systems-management infrastructure, such as System Center Configuration Manager 2007 . Hybrid images use a combination of both strategies . The deployment strategy you choose determines how you build images . After careful planning, you repackage the applications that don t provide an automated installation and document the installation commands for those that do . Then add applications to your MDT 2010 deployment share and add steps to the task sequence that installs the
