Side-by-Side Execution

Side-by-side execution is the ability to install multiple versions of code so that an application can choose which version of the common language runtime or of a component it uses. Subsequent installations of other versions of the runtime, an application, or a component will not affect applications already installed.

This section describes side-by-side execution, how the runtime determines which version of the .NET Framework assemblies to load, and how to design software to take advantage of side-by-side execution.

Side-by-Side Execution Overview

Describes what side-by-side execution is, why it is important, and what problem it solves.

Side-by-Side Execution Fundamentals

Describes how side-by-side execution works.

Installing Multiple Versions of the .NET Framework

Provides information on installing and using several versions of the .NET Framework.

How to: Use an Application Configuration File to Target a .NET Framework Version

Describes how to create a configuration file that an application can use to target a version of the common language runtime.

Creating Multiple Versions of an Application or Component

Provides information on how to create and deploy applications and components designed for side-by-side execution.

Determining a Servicing Strategy for Applications and Components

Discusses how to create a service model for versioned components and applications.

<supportedRuntime> Element

Describes the configuration schema element that specifies which versions of the runtime are supported by an application.
