LightInject.SignalR doesn't work without LightInject.Interception

[Hinidu]

Hello! I've just tried to use LightInject.SignalR and got an exception:

System.Reflection.TargetInvocationException was unhandled
  HResult=-2146232828

Installing LightInject.Interception fixes the issue. I didn't register anything in ServiceContainer. I just call serviceContainer.EnableSignalR(hubConfiguration); and this line produces exception above.

It seems like it is needed because of this: https://github.com/seesharper/LightInject/blob/master/LightInject.SignalR/LightInject.SignalR.cs#L98-L99

[seesharper]

That is correct. LightInject.SignalR requires Lightinject.interception. If the NuGet package does not install it, I need to update the package. On Tuesday, December 23, 2014, Pavel Platto [email protected] wrote:

The LightInject.SignalR nuget package still does not automatically include the LightInject.Interceptor package.

@puzsol @seesharper I've just updated my PR #148. I've realized that to specify dependency I should modify .nuspec file rather than packages.config. I understand that it is entirely my fault to not learn how NuGet packages are creating but this issue wouldn't hang so long if someone could comment that PR =\

I didn't omit any of my knowledge on nuget packages :smile: Thanks for working on it.
