GUI Applications Development Using .NET Framework Deploying .NET Applications Deployment is the process of distributing the files that make up an application to install it on the target computers. There are two deployment strategies that can be used to deploy applications. The strategies are: XCOPY Deployment Visual Studio .NET deployment tools Ver. 1.0 Session 14 Slide 2 of 24
- 3. GUI Applications Development Using .NET Framework XCOPY Deployment • The XCOPY command is used to copy the contents of a directory and its subdirectories to a target computer, where target computer is the computer on which you want to run the application. The /s switch • The syntax of the XCOPY command is: indicates that all XCOPY <source path> <target path> /s subdirectories The limitations of XCOPY deployment are: are to be copied as It requires all files such as compiled .exe files, .dll files well. representing components or controls, and resource files. It also requires the installation of the .NET Framework on the target machines. It cannot be used for an application that requires databases and shared components. It is essential that these databases and shared components are installed on every client machine on which the program will be installed. Ver. 1.0 Session 14 Slide 3 of 24

- 24. GUI Applications Development Using .NET Framework Summary (Contd.) Configuration files are XML files that are used to change the application settings without recompiling an application. There are three types of configuration files. These are: • The Application configuration files • The Machine configuration files • The Security configuration files Configuration sections are used in the configuration files to specify the information that the application reads at run-time. The .NET Framework provides several mechanisms for protecting resources and code from the unauthorized code and users. This includes: Code access security Role-based security Ver. 1.0 Session 14 Slide 24 of 24
Editor's Notes
- #2: Start the session by sharing the session objectives with the students.
- #3: Using this slide, discuss with the students that after an application is created, it needs to be installed on the target machine for the users to use it. Since an application may consist of several files it is essential that all the different files must be packaged and then deployed on the target computer. This ensures that none of the files are missed. Discuss the two different strategies for deploying the application using the following slides.
- #4: Using this slide, explain the purpose and syntax of XCOPY command. Also discuss with the students that XCOPY command has several limitations because of which Visual Studio .NET Deployment Tools are used.
- #5: Use this and the next slide to discuss with the students that the deployment tool helps to package all the required files. In addition, it helps to perform several other tasks as well. It would be a good teaching practice to demonstrate the deployment process to the students.
- #7: Reiterate the concepts taught earlier by asking the given question.
- #8: Use this slide to discuss the deployment process and deployment project editors(in brief). The faculty must insist that the students read about the project editors from the SGs at their home.
- #9: Conduct the activity stated in the slide in a collaborative mode in the class.
- #10: Conduct the activity stated in the slide in a collaborative mode in the class.
- #11: Use this slide to discuss this new feature, “ClickOnce” for packaging and deploying the Visual Studio .NET projects. Also discuss with the students that there are two activities in the chapter that will help them to understand the process used by ClickOnce in a better manner.
- #12: The faculty can just iterate through these steps verbally as there are two activities in the next sections that will help to demonstrate the ClickOnce feature for packaging and deploying applications.
- #13: Conduct the activity stated in the slide in a collaborative mode in the class.
- #14: Conduct the activity stated in the slide in a collaborative mode in the class.
- #15: Conduct the activity stated in the slide in a collaborative mode in the class. Note: The faculty must ensure that IIS is installed for conducting this activity
- #16: Conduct the activity stated in the slide in a collaborative mode in the class.
- #17: Discuss with the students that several configuration files are created to specify certain settings. The biggest advantage of these configuration files is that settings can be applied without having to recompile the applications.
- #18: Discuss the three types of configuration files. You can use the following content from the SG to explain the three types of files: Application configuration files provide a way of overriding the metadata in assemblies without having to rebuild the application. The name of an application configuration file is the name of the application with the .config extension. For example, an application called myApplication.exe will have a configuration file called myApplication.exe.config. Machine configuration files include settings, such as security settings that are applied to all the files of a computer. The name of a machine configuration file is machine.config. The location of this file is: %SystemRoot%\\Microsoft.NET\\Framework\\<Version>\\CONFIG\\ Here, <Version> represents the version of the .NET Framework installed on the machine. Security configuration files contain information about permission sets and code group hierarchy. A permission set is a group of permissions that can be associated with a group of code. A code group consists of a membership condition and a set of permissions. These files contain information related to the code access security system. The following topics discuss in detail about the application configuration file. This is because we are mainly concerned with the configuration of applications
- #19: Reiterate the concepts taught earlier by asking the given question.
- #20: Using this and the next slide, discuss the application configuration files with the students. The faculty can also use the table given in the SG to discuss some common elements included in an application configuration file.
- #21: Using this and the next 2 slides, discuss with the students that an application needs to be secured from unauthorized access. This is because if any changes are made in the code the application may not execute at all unless the entire application is recompiled, packaged, and deployed. Also, if any of the resources are made unavailable, the application may not execute at all.
- #24: You can summarize the session by using the summary given in the slides. In addition, you can also ask students summarize what they have learnt in this session.
