Could not load type with LightInject.Interception + Microsoft DI

[blipson89]

I'm getting a type load yellow screen when trying to load an MVC controller that has a dependency. I'll post the yellow screen at the bottom of this. I'm using Microsoft Dependency Injection. The container registration is in one project (let's call it ProjectDI), and the class the controller that's throwing an error is in another project (let's call it ProjectMVC).

ProjectMVC references ProjectDI. The dependency (CreatorLog) is being registered in ProjectMVC by adding it to the IServiceCollection. The intercept code in ProjectDI gets the list of ServiceDescriptors and registers them like this:

foreach (ServiceDescriptor descriptor in serviceCollection)
{
    string assemblyName = descriptor.ServiceType.AssemblyQualifiedName ?? "";
    if (WhitelistedAssemblies.Any(assemblyName.StartsWith))
    {
        container.Intercept(s => s.ServiceType == descriptor.ServiceType, i => new MiniProfilerInterceptor());
    }
}

The stack trace I'm getting is:

The MVC controller is registered, as is the dependency.

Can you create a small repro that we can PR into?

[blipson89]

Thanks for the quick reply! I'll see if I can reproduce it on a smaller scale and circle back with you.

@seesharper I'm going to close this one out. It seems to be working fine now. I think there was an underlying issue with a dependency somewhere far down the rabbit hole and the error in the stack trace I posted was probably just a red herring.

I'm enjoying LightInject so far - thank you for the support!

[seesharper]

Good stuff :)
