Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IRegistrationBuilderTLimit, TActivatorData, TRegistrationStyle. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

While you can implement an IStartable to perform some logic at container build time, sometimes you need to just activate a registered component and that's it. This extension allows you to automatically activate a registration on container build. No additional logic is executed and the resolved instance is not held so container disposal will end up disposing of the instance.

Depending on how you register the lifetime of the component, you may get an exception when you build the container - components that are scoped to specific lifetimes (like ASP.NET components scoped to a request lifetime) will fail to resolve because the appropriate lifetime is not available.
