4 - Packaging and the Runtime

Environment

Application packaging is the process of bundling an application and

its resources into an archive format for distribution and deployment.

The App Container

• When a Web app executes, it does so in a contained environment
  
  
  • An app container is a separate memory space
  
  
  
  


• The purpose of an app container is to prevent apps from corrupting

the operating system

Permissions are grouped into permission sets, and every assembly is

assigned a set. The .NET Framework defines some standard permission sets

such as FullTrust (implies all permissions) and Execution (permission to

access the CPU only).

Each user account is assigned a level of access (credentials). They can

be set to use Windows Authentication, database authentication, no

authentication, or custom authentication.

The Windows Runtime environment is the foundation of the

Windows 8 operating system and provides functionality to Metro-style apps.

When you launch an app, it’s considered to be in a runtime

environment (RTE). An RTE is where users run the app and developers test

it. In Windows, this environment is called Windows Runtime (WinRT).
