Version of Unity Application Block released in March 12

In March 12, unity released a version earlier than the official release. This version provides the installer and a configuration API for dependency injection implementation: setter injection. In the previous version, [dependency] is required for property injection. This design unity will intrude into your components. You can use configuringinjection.

For example, stoplightpresenter depends on stoplight and stoplightschedule. You can tag [dependency] In the attribute or remove this tag, and then configure the API in unitycontainer by configuring the following:

Public class stoplightpresenter
{
Private stoplight;
Private stoplightschedule schedule;

// [Dependency]
Public stoplight
{
Get {return stoplight ;}
Set {stoplight = value ;}
}

// [Dependency]
Public stoplightschedule schedule
{
Get {return schedule ;}
Set {Schedule = value ;}
}

Private istoplightview view;

......

}

The configuration code is as follows:

Iunitycontainer Container = new unitycontainer ()
. Addnewextension <simpleeventbrokerextension> ()
. Registertype <ilogger, tracelogger> ()
. Registertype <istoplighttimer, realtimetimer> ();
Container. Configure <injectedmembers> ()
. Configureinjectionfor <stoplight. Logic. stoplight> (
New injectionproperty ("logger ")
);

Container. Configure <injectedmembers> ()
. Configureinjectionfor <stoplightpresenter> (
New injectionproperty ("stoplight "),
New injectionproperty ("Schedule ")
);

Although the development of the Unity Application Block is not long, it is mainly based on the development of objectbuilder that emerged from enterprise class library 2.0. The next Microsoft Enterprise Library version V4-injection of Preset support dependency. Dependency injection is provided by containers independently or as part of the database.
