Useful little bits for FubuMVC; rather than dig through source, keeping them here for quick reference. I'll eventually post an article with them that's better for public consumption.

// If using FubuAthentication, update auth ticket as needed (e.g. account creation or key updated)
private readonly IAuthenticationSession _auth;
public SomeController(IAuthenticationSession auth) { _auth = auth; }
_auth.MarkAuthenticated(user.Email);

// If using FubuAuthentication, make route available to anonymous users
[NotAuthenticated]
public FubuContinuation SomeRoute(SomeRouteInputModel input)
{
    // Use a continuation to redirect to input-less page
    return FubuContinuation.RedirectTo<HomeController>(x => x.HomePage());
}

// Use the url registry to grab links (better than handcoding, as this way you're safe if app is nested)
private readonly UrlRegistry _urlregistry;
public SomeController(UrlRegistry urlreg) { _urlregistry = urlreg; }
// input-based route
string sUrl = _urlregistry.UrlFor(new SomeInputModel { Id = input.Id })
// input-less route
string sUrl = _urlregistry.UrlFor<HomeController>(x => x.HomePage(), "GET");

// Within a Spark view, you can link and add various <a> metadata (method returns an HtmlTag and can be chained)
${this.LinkTo[[MyNamespace.Handlers.AboutController]](c => c.AboutUs()).AddClass("nav").Text("About Us")}
// You can also include an image
${this.LinkTo[[MyNamespace.Handlers.HomeController]](c => c.HomePage()).Append(this.ImageFor("home.png"))}

// If you want to have a Fubu partial (which will get its own pipeline; e.g. it can utilize security, 
// even within a route that's not authenticated
${this.Partial<MyNamespace.Handlers.TopNavInputModel>()}

// You can uses a bindings.xml file in your web apps Shared folder to utilize tags for calls
<element name="Image">this.ImageFor('@src')</element>
// With the above, instead of using ${this.ImageFor("home.png")} we can use:
<Image src="home.png"/>
