UnityConfiguration v1.4.1

Convention based configuration for the Microsoft Unity IoC container. With just a few lines of code, you can now registere all your classes in the entire solution. If the built-in conventions doesn't fit your needs, it is very easy to extend with your own.

Download and install

UnityConfiguration is available for download on NuGet.

To install it run the following command in the NuGet Package Manager Console.

PM> Install-Package UnityConfiguration

This will download all the binaries, and add necessary references to your project.

Configuring your container

You get access to the configuration api by using the extension method Configure on the IUnityContainer interface.

var container = new UnityContainer();
container.Configure(x =>
	x.AddRegistry(new BarRegistry());

Configure using registries

Configuration is done in one or several registries that inherit the UnityRegistry base class.

public class FooRegistry : UnityRegistry
	public FooRegistry()
		// Scan one or several assemblies and auto register types based on a 
		// convention. You can also include or exclude certain types and/or 
		// namespaces using a filter.
		Scan(scan =>

		// Manually register a service
		Register<IFooService, FooService>().WithName("Foo").AsSingleton();

		// Make services a singleton. Useful for types registered by the scanner.

		// If you want to inject values or objects that are not registered in
		// the container, you can do so by adding them using this statement.
		// For instances you want the container to create, just specify the type.
		Configure<ServiceWithCtorArgs>().WithConstructorArguments("some string", typeof (IFooService));

		// Unity follows the greedy constructor pattern when creating instances.
		// If you want to use a different constructor, you specify it by listing 
		// the types of the arguments in the constructor you want it to use.
		SelectConstructor<ServiceWithCtorArgs>(typeof (IFooService));

		// You can automatically configure the container to call
		// a method on any service when they are created
		AfterBuildingUp<IStartable>().Call((c, s) => s.Start());

		// You can automatically configure the container to 
		// decorate services when they are created
		AfterBuildingUp<IFooService>().DecorateWith((c, t) => new FooDecorator(t));

Custom conventions

At the moment, built in conventions includes AddAllConvention, FirstInterfaceConvention, NamingConvention, SetAllPropertiesConvention and ScanForRegistriesConvention. If these doesn't suit you, creating custom conventions is as easy as creating a class that implements the IAssemblyScanner interface.

public class CustomConvention : IAssemblyScannerConvention
	void IAssemblyScannerConvention.Process(Type type, IUnityRegistry registry)
		if (type == typeof(FooService))
			registry.Register<IFooService, FooService>().WithName("Custom");

Release Notes


  • Fixed #6: AssemblyScanner not bin folder friendly for web apps
  • Added #5: IUnityContainer.Configure() returns the IUnityContainer so other calls can be chained


  • Added extension methods to the IAssemblyScanner for easier discovery and configuration of conventions
  • Added non-generic overload to the AddAllConvention
  • Added option to scan for internal types in an assembly - IAssemblyScanner.InternalTypes()
  • Strong named the assembly
  • Switched to Semantic Versioning


  • Documented public facing methods
  • Included the xml documentation in the NuGet package
  • Debugging symbols are available on
  • Several more overloads for adding assemblies to the scanner
  • One more overload for adding a registry that takes an instance of a UnityRegistry
  • New convention that scans for registries
  • New convention that uses an overridable naming convention for registering a type mapping
  • MakeSingleton() and MakeSingleton(string) is marked as obsolete. Use Configure().AsSingleton() or Configure().WithName(name).AsSingleton() instead
  • ConfigureCtorArgsFor(params object[] args) is marked as obsolete. Use Configure().WithConstructorArguments(params object[]) instead
  • Added Transient, PerThread, PerResolve, ExternallyControlled and HierarchicalControlled lifetime scope configuration
