Desktop Application Deployment
This section covers the various strategies and tools available for deploying your .NET desktop applications to end-users. Choosing the right deployment method depends on your application's complexity, target audience, and update requirements.
Deployment Technologies
ClickOnce Deployment
ClickOnce is a technology that enables developers to deploy and update Windows applications that have minimal user interaction. It provides a simplified installation and update experience for end-users.
- Advantages: Easy installation, automatic updates, no administrative privileges required for installation (for per-user deployments), rollback to previous versions.
- Scenarios: Small to medium-sized applications, internal business applications, applications distributed via the web or network shares.
Key Features:
- Web-based installation
- Network share installation
- Media-based installation (CD/DVD/USB)
- Application manifests
- Publishing profiles

MSI Packaging (Windows Installer)
Windows Installer (MSI) is the standard Windows installation package format. It's a robust and flexible technology for deploying applications, managing upgrades, and handling uninstallations.
- Advantages: Comprehensive control over installation process, silent installations, custom actions, repair functionality, integration with Group Policy.
- Scenarios: Enterprise deployments, applications requiring complex installation logic, applications that need to be installed for all users on a machine.
Tools for MSI creation:
- Visual Studio Installer Projects Extension
- WiX Toolset
- Advanced Installer
- InstallShield

Microsoft Store Deployment
Distribute your applications through the Microsoft Store, reaching a wide audience of Windows users. This provides a managed environment for app discovery, installation, and updates.
- Advantages: Discoverability, automatic updates, secure download and installation, sandboxing for enhanced security.
- Scenarios: Consumer applications, UWP applications, desktop applications packaged as MSIX.

Self-Contained Deployments
With self-contained deployments, the .NET runtime and libraries are bundled with your application. This eliminates the need for end-users to install the .NET runtime separately.
- Advantages: No pre-requisite runtime installations, guaranteed compatibility, easier for users with no prior .NET setup.
- Disadvantages: Larger application size due to bundled runtime.
This is often used in conjunction with other deployment methods like MSI or ClickOnce.
Choosing the Right Deployment Method
Consider the following factors when deciding on a deployment strategy:
- Target Audience: Are your users individual consumers or enterprise users?
- Update Frequency: How often will you release updates?
- Installation Complexity: Does your application require custom configurations or dependencies?
- Security Requirements: Are there specific security policies to adhere to?
- Distribution Channel: Will you distribute via web, network, or app store?
