I'm considering porting an existing ASP.NET MVC3 application onto Nancy.
The application currently makes heavy use of the html helper extension RenderAction.
I can't work out how to replicate this behaviour in Nancy. Any ideas?
It's not supported out of the box - while it's possible, it's also going to be a reasonable amount of work and will require you knowing quite a bit about Nancy's guts to implement. We support rendering partials, but not rerunning the whole request stack (which is essentially what RenderAction does).
