Access or get Autofac Container inside a static class

Question

I need to get or access to my IoC container in a static class. This is my (simplified) scenario:

I register dependencies for ASP .net Web Api in a Startup class (but als

You can create a static method inside your DomainEvents class to inject the container like this:

public static class DomainEvents
{
    public static void SetContainer(IContainer container)
    {
        Container = container;
    }

    ....
}

And then from your ASP.NET application, call this method to inject the container:

DomainEvents.SetContainer(container);

Please note that I am giving you a direct answer to your question. However, here are some issues that I see with this:

• Static classes should not be used when the class requires dependencies. In such case, refactor to use a non-static class and use Constructor Injection to inject the dependencies that you need in the class.
• Using the container outside of the Composition Root is called Service Location and is considered an anti-pattern.
• Class libraries should not use the container or even have a Composition Root. Quoting from the Composition Root article that I referenced:

Only applications should have Composition Roots. Libraries and frameworks shouldn't.
