I'm talking supported builds, not signed builds. You know with the pile of pre-paid support credits that we get with our partnership agreement which are supposed to result in solutions. Every support call requires a week long argument with the lowest grade of software support who phone me up and ask if they can close the call every day without escalating it. I'm aware of the support options you mention, which basically result in "yes, just limp along with the dependency injection problems with ActionFilters in MVC3 for 6 months" or fork and fix it yourself. We chose the latter, but it's expensive so we might as well forfeit the partner agreement, use Open Source software and pay someone to maintain our forks and contribute patches to the products.

We've looked at NDjango, but it's based on F# and as we well know, unless a product is a mainstream MS platform then it's liable to go out of the window on a whim or is shrouded constantly with uncertainty (choke silverlight, original workflow foundation, XNA? etc).

Sorry if this is rather critical and slightly ranty, but I'm slightly pissed off with maintaining this mess.
