Upgrade to 4.0.2 breaks SignalR

[modernist]

When upgrading from version LightInject 4.0.0 to 4.0.2 using LightInject.SignalR integration I get the following exception:

Try upgrading to LightInject.Interception 1.0.0.9 (Just published)

[modernist]

I'm afraid the issue is not resolved with the upgrade to LightInject.Interception 1.0.0.9. I am using .NET 4.6 and It occurs when attempting to replace the Owin GlobalHost.DependencyResolver with a new instance of the LightInjectDependencyResolver class.

The exception occurs in the first line of the LightInjectDependencyResolver class constructor: https://github.com/seesharper/LightInject/blob/master/LightInject.SignalR/LightInject.SignalR.cs#L97

serviceContainer.Register<IHubActivator>(factory => new LightInjectHubActivator(serviceContainer));

Perhaps it is an issue with the conditional compilation directives used in this section: https://github.com/seesharper/LightInject/blob/master/LightInject/LightInject.cs#L208 because LightInject is compiled for .NET 4.6 whereas LightInject.SignalR is compiled for .NET 4.5. Therefore it could just be an issue with the binaries available on NuGet - I haven't checked with the source versions.

@modernist I don't know if you're still fighting this issue. I was running into the same problem this morning. I ended up fixing it by switching to the latest source NuGet package and adding #define NET45 to the head of the LightInject.cs file. After that I was able to compile and launch my project without issue.

I have the same issue, also using .NET 4.6.

I am now hitting this issue. I can not use the source packages (because I am exposing the ServiceContainer to another project, and all of the types in the source packages are internal).

This means I am currently blocked on getting LightInject to work with SignalR.

I am using .NET 4.5.1, but I tried re-targetting to both .NET 4.5 and .NET 4.6 and re-installing all affected packages, and all LightInject packages, and the issue was still happening.

Versions:

• LightInject 4.0.11
• LightInject.Web 1.0.0.7
• LightInject.WebApi 1.0.0.4
• LightInject.Mvc 1.0.0.4
• LightInject.Interception 1.0.0.11
• LightInject.SignalR 1.0.0.1

I had to workaround this issue by not using LightInject.SignalR, but manually registering my hub with the SignalR dependency resolver:

var hubConfiguration = new HubConfiguration();
hubConfiguration.Resolver.Register(typeof(MyHub), Container.Create<MyHub>());
app.MapSignalR(hubConfiguration);

This enables constructor injection in the hub, using services already registered in the LightInject Container.

I will move SignalR into its own repo and add specific support for Net46
