Autofac Examples

Example projects that consume and demonstrate Autofac functionality and integration.

The Examples

Each example has its own README with what it shows and how to run it.

ASP.NET Core

Example	Demonstrates	Packages
AspNetCoreExample	A Startup class whose ConfigureContainer takes a ContainerBuilder	Autofac.Extensions.DependencyInjection
AspNetCoreNoStartupExample	The same wiring in the minimal hosting model, with no Startup class	Autofac.Extensions.DependencyInjection
AspNetCoreChildLifetimeScope	Two hosts sharing one container, each rooted in its own child scope	Autofac.Extensions.DependencyInjection
MultitenantExample.AspNetCore	Per-tenant registration overrides, with the tenant read from the query string	Autofac.AspNetCore.Multitenant

Hosting and core features

Example	Demonstrates	Packages
GenericHostBuilderExample	The generic host without ASP.NET Core, for worker services	Autofac.Extensions.DependencyInjection
ConfigurationExample	Registering from autofac.json, including an unreferenced plugin assembly	Autofac.Configuration
AttributeMetadataExample	Metadata by string, class, interface, and attribute, then filtering on it	Autofac.Extras.AttributeMetadata
MultitenantExample.ConsoleApplication	Per-tenant overrides with no web request in sight	Autofac.Multitenant
DynamicProxyExample	Method interception, wired both on the registration and by attribute	Autofac.Extras.DynamicProxy
PoolingExample	Reusing expensive instances across scopes, with a reset-on-return policy	Autofac.Pooling
DotGraphExample	Capturing a resolve operation as a Graphviz graph for troubleshooting	Autofac.Diagnostics.DotGraph
MiddlewarePipelineExample	Resolve middleware for auditing, timing, caching, ambient state, and scope guards	Autofac

.NET Framework

These target net481 and need Windows. Most run under IIS Express from Visual Studio.

Example	Demonstrates	Packages
MvcExample	MVC 5 controllers, action filters, and view pages, plus a WCF client	Autofac.Mvc5, Autofac.Wcf
WebFormsExample	Property injection into pages that cannot take constructor arguments	Autofac.Web
WcfExample	A WCF service whose implementation is resolved from the container	Autofac.Wcf
WebApiExample.OwinSelfHost	Web API 2 self-hosted under OWIN instead of IIS	Autofac.Owin, Autofac.WebApi2, Autofac.WebApi2.Owin
MultitenantExample.WcfService	A WCF service resolving a different implementation per tenant	Autofac.Multitenant.Wcf, Autofac.Wcf
MultitenantExample.MvcApplication	The client half, carrying tenant identity across the service boundary	Autofac.Multitenant, Autofac.Mvc5

ConfigurationExampleInterface and ConfigurationExamplePlugin are supporting libraries for ConfigurationExample rather than examples themselves.

Reading the Examples

The examples in the repo are always for the latest Autofac versions and libraries. Look at the tags on this repo to see examples for older and/or deprecated functionality.

The examples attempt to stick pretty close to the Autofac documentation so it helps to have that available.

Open this repo in Visual Studio Code.

Building the Examples

Examples.slnx contains every sample. The ASP.NET MVC, Web Forms, WCF, and OWIN self-host samples target .NET Framework, so building the whole solution requires Windows; the rest build anywhere.
