Autofac exception - security critical vs level 2 security transparency
I'm updating an older project to use .net 471 instead of 462 and the most recent version of all nuget packages.
I've had a lot of versioning issues to plow through, but I finally got a project that builds.
But, when I execute the programming I get this exception:
System.TypeAccessException: 'Attempt by security transparent method
'Autofac.Integration.WebApi.RegistrationExtensions.RegisterApiControllers(Autofac.ContainerBuilder,
System.Reflection.Assembly)' to access security critical type
'Autofac.Builder.IRegistrationBuilder`3'
failed.
Followed by
Assembly 'Autofac.Integration.WebApi, Version=3.0.0.0,
Culture=neutral, PublicKeyToken=17863af14b0044da' is marked with the
AllowPartiallyTrustedCallersAttribute, and uses the level 2 security
transparency model. Level 2 transparency causes all methods in
AllowPartiallyTrustedCallers assemblies to become security transparent
by default, which may be the cause of this exception.'
That happens when calling:
builder.RegisterApiControllers(ThisAssembly);
Where builder is an Autofac ContainerBuilder.
Question
Like the subject says, it must be some kind of conflict between SecurityCritical and AllowPartiallyTrustedCallersAttribute but I don't know how I've introduced it and what the best action is, so
What's going on and how can I fix this?
Update
Going further on JLe's suggestion, I removed the webapi reference and used webapi2 instead. I got a related error on my logging setup, but since that's not "core functionality" I skipped it for now (I will need to get back to that) to see what I'd get. I get to the browser screen, which gives me this:
Method 'my.namespace.MyController+d__6.MoveNext()' is
security transparent, but is a member of a security critical type.
I tried putting [SecurityCritical] on the controller class, but apparently you're not allowed to do async calls in a class with that attribute:
Error CS4031 Async methods are not allowed in an Interface, Class, or
Structure which has the 'SecurityCritical' or 'SecuritySafeCritical'
attribute.
But I can't fix that, because I'm doing async calls to the backend (NServicebus ESB).

I'm just guessing, but the Autofac.WebApi2 package is for WebApi2, so I though maybe the old package created some version conflict which lead to your exception. Could you try remove the old one?

Nov 26 '18 at 13:35
Have you tried cleaning your solution? The WebApi2 package should contain those as well, version 4.2.0. The actual namespace of it is the same, Autofac.Integration.WebApi even though it's version 2.

@JLe: Your suggestion about cleaning up the packages ultimately fixed it (by making sure I was using webapi2). Could you write an answer so I can accept it?

Make sure you're using nuget.org/packages/Autofac.WebApi2 as that one if for WebApi2, and not the older one called just Autofac.WebApi (the namespaces are the same though, Autofac.Integration.WebApi).
