Solving Autofac issue Inheritance security rules violated while overriding member GetService

Question

I've got an ASP.NET MVC application using Autofac.

I've added the appropriate packages via:

Install-Package Autofac
Install-Package Autofac.Mvc4

When I ran the web application, this error was throw:

Inheritance security rules violated while overriding member: 'Autofac.Integration.Mvc.AutofacDependencyResolver.GetService(System.Type)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

How can this be solved?

Answer 1

I had installed Autofac for MVC 4 when the project type was actually MVC 5.

To solve this, I ran Uninstall-Package Autofac.Mvc4 and

Install-Package Autofac.Mvc5
