On initial warmup after creating a Blog you get lifescope issues with BlogPathConstraintUpdator


Create a Blog.
Restart you Cassini instance.
F5 with exceptions on.

You should end up with this exception:

No scope with a Tag matching 'work' is visible from the scope in which the instance was requested. This generally indicates that a component registered as per-HTTP request is being reqested by a SingleInstance() component (or a similar scenario.) Under the web integration always request dependencies from the DependencyResolver.Current or ILifetimeScopeProvider.RequestLifetime, never from the container itself.

public interface IForumPathConstraint : IRouteConstraint, ISingletonDependency {

Even with sebs fix still experienced this issue. Fixed again by wrapping the IBlogService variable in the BlogPathConstraintUpdator class in a Lazy<IBlogService> and amending the class accordingly. Note by fixed I mean the exception has gone away; no further testing done yet.
