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


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.

Visual Studio .NET Deployment Tools

Using this method, you can package all the files and
components that make up the application and create a
setup program.
This setup program can be used to perform the following
tasks:
Copy all the necessary files to the target computer
Store files in appropriate folders
Create the necessary registry entries
Create a Start menu item
Create an icon on the desktop to access the application
Let us see how an application can be packaged and
deployed in .NET.


Visual Studio .NET Deployment Tools (Contd.)

To create a setup program for an application, Visual
Studio .NET provides a special project type called Setup
and Deployment Project.
This project type provides various templates for deploying
various types of applications. These templates are:
Setup Project
Web Setup Project
Merge Module Project
Cab Project
Setup Wizard Project
Smart Device Cab Project


Just a minute

What is the extension of the Windows Installer file?

Answer:
.msi


Using Deployment Project Editors

Deployment project editors help to customize various
things. Two of them are:
Specifying files and folders to be included in the deployment
project.
Creating registry entries when the application is deployed.
To perform these tasks, Visual Studio .NET provides the
following editors in deployment projects:
File System Editor
Registry Editor
File Types Editor
User Interface Editor
Custom Actions Editor
Launch Conditions Editor


Demo: Deploying and Installing a Project

Problem Statement:
The development of the EmployeeReport application is
complete. The application now needs to be shipped to the
client so that it can be installed on a user computer. The
installation process should perform the following tasks:
• Copy all application files to a user computer.
• Create a shortcut on the desktop of a computer to start the
application.
When a user begins installation, a license agreement should
be displayed to the user. The process of installation should
proceed only when a user accepts the license agreement.
Help the programmer to create the installer for the application.


Demo: Deploying and Installing a Project (Contd.)

Solution:
To solve the preceding problem, you need to perform the
following taks:
1. Create a deployment project.
2. Add the application files to the deployment project.
3. Create a shortcut of the application.
4. Add a license agreement to the deployment project.
5. Build the solution and execute the installer.


Implementing ClickOnce

ClickOnce is a new application deployment technology
provided by Microsoft Visual Studio 2005.
A ClickOnce application provides automatic updates and
installation from:
a Web page,
network file share, or
a CD-ROM
It allows you to create applications that provide easy
installation and good user interfaces.
For creating the ClickOnce application, you can use the
Publish Wizard in Visual Studio 2005 to package the
application and publish it to a Web site or network file share.


Deploying an Application Using ClickOnce

To deploy an application using ClickOnce, you need to
perform the following steps:
1. Open Visual Studio 2005 and open the project.
2. Build the project and ensure that there are no compilation
errors.
3. Execute the application and ensure that it meets required
specification.


Demo: Publishing a ClickOnce Application

Problem Statement:
Package and deploy the EmployeeReport application at the
local machine using ClickOnce.
Help the student to develop the required application.


Demo: Publishing a ClickOnce Application (Contd.)

Solution:
To meet the preceding requirement, you need to perform the
following tasks:
1. Open the EmployeeReport project.
2. Prepare the application for deployment.
3. Publish the application.


Demo: Publishing a ClickOnce Application at the Web Server

Problem Statement:
Package and deploy the EmployeeReport application at Web
server using ClickOnce.


Demo: Publishing a ClickOnce Application at the Web Server
(Contd.)

Solution:
To meet the preceding requirement, you need to perform the
following tasks:
1. Open the EmployeeReport project.
2. Prepare the application for deployment.
3. Publish the application.


Configuration Files

Configuration files are generally Extensible Markup
Language (XML) files that contain configuration options,
such as:
starting options
maximum resource usage options for applications
These files are used to:
change application settings without recompiling the
applications.
set machine policies, which affect the way applications run on
a computer.
These files can be modified whenever required.
Configuration files are case sensitive.


Types of Configuration Files

There are three types of configuration files. These are:
Application configuration files
Machine configuration files
Security configuration files


Just a minute

Identify the root element in every configuration file that is
used by the CLR and .NET Framework applications.
1. <runtime>
2. <config>
3. <configuration>
4. <assemblybinding>

Answer:
3. <configuration>


Configuring Applications

The .NET Framework allows developers and administrators
to control the way applications run by changing the
application settings in the application configuration file.


Securing Windows Applications

The security of any computer can be maintained by
authenticating a user.
Similarly, applications also need to be secured from
unauthorized access or virus-attack.
There are several mechanisms to secure an application in
the .NET environment.
The mechanisms for protecting resources and code from
unauthorized code and users include:
– Code access security: Controls the resources that your code
can access.
– Role-based security: Allows developers to limit the users who
can run certain parts of the application.


Code Access Security

The Code Access Security (CAS) consists of elements such
as:
Evidence
Permissions
Permission sets
Code groups
Security Policy


Role-Based Security

Role-based security uses the Principal and Identity objects
to access information about the user.
The identity object consists of the user’s login name.
Principal object consists of the information about the role of
the user.


Summary

In this session, you learned that:
After creating an assembly for a component, you can create a
deployment project to deploy the component.
Deployment is the process of distributing the files that
constitute an application.
There are two common deployment strategies available with
.NET. These are:
• XCOPY Deployment
• Setup and Deployment projects
– The Setup and Deployment Project type provides a number of
templates for deploying various types of applications.
– The Setup Wizard exists as a simple step-by-step project
creation facility.
– Visual Studio .NET provides several editors in deployment
projects.


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
