Problems when Upgrading from 3.2.1 to 3.2.2 - ICache Error

[squadwuschel]

Hi,

I have a Project, where I am using the following Ninject Components:
with this Confoguration everything works fine

<package id="Ninject" version="3.2.2.0" targetFramework="net40" />
<package id="Ninject.MVC4" version="3.2.1.0" targetFramework="net40" />
<package id="Ninject.Web.Common" version="3.2.1.0" targetFramework="net40" />
<package id="Ninject.Web.Common.WebHost" version="3.2.1.0" targetFramework="net40" />

When I update the Ninject.Web.Common to:

<package id="Ninject.Web.Common" version="3.2.2.0" targetFramework="net40" />

I get the following Error, when I am calling the Website:

Error loading Ninject component ICache
No such component has been registered in the kernel's component container.

Suggestions:

1. If you have created a custom subclass for KernelBase, ensure that you have properly
   implemented the AddComponents() method.
2. Ensure that you have not removed the component from the container via a call to RemoveAll().
3. Ensure you have not accidentally created more than one kernel.

Would you mind send a sample demo to me?

I have the same issue, is there a solution for that?

Unfortunately, I cannot post example code for my issue here because of policies with my customer.
But I figured out that the error appears when I use a second Kernel instance that is disposed.

Is it possible to use multiple Kerne instances with this Framework?

Let me describe my context a littlebit:

I multiple Plugins for dedicated Tasks in my App.
A Plugin can be hosted in an API, an Azure WebJob or in other Environments like UnitTests, ConsoleApps, etc.

Every Plugin has it's own Kernel and own DI registrations.
In that specific case is a Plugin hosted in an API.
It is created and disposed on a specific WebApi Action call.
When the Request is done (the Action method is leaved) the Plugin (and his Kernel) will be disposed.
When that happened I will get everytime that error.
Calls to other actions will then also fail (also to complete empty actions).

I looked into your code and find that line here.

And if I check the base class GlobalKernelRegistration MapKernels method it looks like Kernels are stored as WeakReferences by Ninject.
At the end of this method kernels that are no longer alive (!reference.IsAlive) will be removed.
But such kernels will be passed to the action callback.
Because of that Exception the dead kernel could not be removed and that error will happen on next request also.
Maybe it would help simple hide that Exception on your code?
