Issue with latest version of Autofac

[GoogleCodeExporter]

We've been using Autofac for a while now in our .NET and SL4 code. I tried to 
upgrade to 2.6.2.859 tonight, and all tests passed save for one in the SL4 
code. The test builds up a ContainerBuilder, and when this line of code is 
called:

var viewModel = builder.Build().Resolve<MainViewModel>();

the following exception is thrown:

Autofac.Core.DependencyResolutionException occurred
  Message=An exception was thrown while executing a resolve operation. See the InnerException for details.
  StackTrace:

       InnerException: 

This didn't happen with the previous version. Our .NET code does not have any 
issues; only the SL4 one does.

Any insight as to why this is suddenly failing?

Thanks for the report, Jason. We made some optimisations in the 2.6.2 release 
that appear to be incompatible with the Silverlight security model, we'll look 
into this. In the meantime, rolling back to 2.6.1 is the best idea.

Cheers,
Nick

I am fairly sure that rev 941 fixes the issue; it removes the LambdaExpression 
code from the Silverlight build. The WINDOWS_PHONE condition has been replaced 
with SILVERLIGHT because that condition is defined for both the Silverlight and 
WP7 builds. I figured that as we move towards Portable Libraries support that 
any code that does not work across all supported targets for the profile should 
be excluded.
