How to set up your first application wide Autofac service locator

So you've decided to go the modular route and you're ready to set up your ServiceLocator project as outlined here? Let's do this.

Install the GSoft.Dynamite NuGet package in your empty Company.Project.ServiceLocator.dll project (as a matter of convention, it is important that your assembly file name respects the pattern "*.ServiceLocator.dll").

Add a class to your project, name it ProjectContainer. Start by populating it like this:

// The Container that is used by WSPs for dependency injection across 
// all Company.Project.*.WSP projects
public class ProjectContainer
{
    // The key that distin
    private const string AppName = "Company.Project";

    // The locator will scan the GAC and load the following Autofac registration modules:
    // - the core Dynamite utilities registration module
    // - all registration modules from assemblies with a filename that starts with "Company.Project"
    private static ISharePointServiceLocator locatorInstance = new SharePointServiceLocator(AppName);
}

This is the core of the service locator/container. The interface ISharePointServiceLocator comes from the namespace GSoft.Dynamite.ServiceLocator and provides SharePoint-aware dependency injection capabilities. The implementation SharePointServiceLocator will scan the GAC using the AppName as a pattern to match assembly file names (as a convention).

Of course, Dynamite's own type registration module will be loaded earlier during bootstrapping (note that this allows you to override Dynamite's own type registrations with your own alternate implementations - effectively replacing Dynamite's default implementations with your own across the Container's domain).
