Ninject.MockingKernel.Moq security exception

问题

I am using Ninject for my IoC container and I'm trying to write some unit tests. I found the Ninject Mocking Kernel so I thought I'd give it a go but I can't get the simplest test to pass. I am missing something and need a little help.

Moq.4.0.10827.Final Ninject-2.2.0.0-release-net-4.0 Ninject.MockingKernel-2.2.0.0-release-net-4.0

My unit test...

    [TestMethod]
    public void Constructor_CanInitialize()
    {
        var kernel = new MoqMockingKernel();

        var mock = kernel.Get<IDataRepository>(); <--Error here

        Assert.IsInstanceOfType(mock, typeof(DataRepository));
    }

Here is the error...

Test method TestFixture.Constructor_CanInitialize threw exception: System.TypeAccessException: Attempt by security transparent method 'Ninject.MockingKernel.Moq.MoqMockProvider.Create(Ninject.Activation.IContext)' to access security critical type 'Moq.Mock' failed.

Assembly 'Ninject.MockingKernel.Moq, Version=2.2.0.0, Culture=neutral, PublicKeyToken=c7192dc5380945e7' 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.

I have been fighting the same problem for a little while now. See this thread to follow my effort: https://groups.google.com/d/topic/ninject/xInlcd2b1l8/discussion

Assuming that you are using NuGet you have two options:

• Don't use Ninject.MockingKernel right now or
• build it from source yourself.

Any way you may want to keep a tab on the project to use it via NuGet again once an updated version is available.

Late to the party, but this works:

var mock = kernel.GetMock<IDataRepository>();
