Adding Unity to Your Application

Unity is designed to support a range of common scenarios for resolving instances of objects that, themselves, depend on other objects or services. However, you must first prepare your application to use Unity. The following procedure describes how to include the necessary assemblies and elements in your code.

To prepare your application

  1. Add a reference to the Unity assembly. In Visual Studio, right-click your project node in Solution Explorer, and then click Add Reference. Click the Browse tab and find the location of the Microsoft.Practices.Unity.dll assembly. Select the assembly, and then click OK to add the reference.
  2. (Optional) If you intend to use the configuration types when you create extensions for Unity, use the same procedure to set a reference to the Unity configuration assembly, named Microsoft.Practices.Unity.Configuration.dll.
  3. (Optional) If you intend to use the interception and policy injection features of Unity, use the same procedure to set a reference to the Unity interception assembly, named Microsoft.Practices.Unity.Interception.dll.
  4. (Optional) If you intend to use the configuration types for the interception and policy injection features of Unity, use the same procedure to set a reference to the Unity interception configuration assembly, named Microsoft.Practices.Unity.Interception.Configuration.dll.
  5. (Optional) To use elements from Unity without fully qualifying the element reference, add the following using statements (C#) or Imports statements (Visual Basic) to the top of your source code file as required.
    'Usage
    Imports Microsoft.Practices.Unity
    Imports Microsoft.Practices.Unity.Configuration
    Imports Microsoft.Practices.Unity.InterceptionExtension
    
  6. (Optional) If you are using the IServiceLocator interface, add a reference to the service location binary Microsoft.Practices.ServiceLocation.dll. Visual Studio may automatically copy this file to your bin directory when it compiles, but you do not need to include it unless you are explicitly using the UnityServiceLocatorAdapter class.
  7. Add your application code. For more information about how you can use Unity in your own applications, see What Does Unity Do?

For Visual Basic projects, you can also use the References page of the Project Designer to manage references and imported namespaces. To access the References page, select a project node in Solution Explorer, and then click Properties on the Project menu. When the Project Designer appears, click the References tab.

There are limitations when using Unity in a partial trust environment. For more information, see Using Unity in Partial Trust Environments.
