Question

I am trying to use the Nancy addin Nancy.LightningCache

According to the docs I should be able to set up my caching easily, like this:

Bootstrapper

protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)
{
    base.ApplicationStartup(container, pipelines);
    this.EnableLightningCache(
            container.Resolve<IRouteResolver>(), 
            ApplicationPipelines, 
            new[] {"id", "claim", "query", "take", "skip"});
}

Route

Get["/profile"] = _ => 
View["UserProfileView", Model].AsCacheable(DateTime.Now.AddSeconds(30)); 

When this route is called I get the following exception.

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:
'Nancy.Responses.Negotiation.Negotiator' does not contain a definition for 'AsCacheable'

Any ideas?

OK, got it.

Working Route

return View["HomeView", (object)Model].AsCacheable(DateTime.Now.AddMinutes(1));

You can see that I have been forced to explicitly cast my Model to an object in order to satisfy the signature of the AsCachable extension method.

The problem only shows up at runtime because my Model is an ExpandoObject and so a dynamic type.
