I don't think you need to consider a pay cut. It's easy to look at HN and think that all of the good jobs are in new technologies and your experience is worthless. That's not the case.

Take a week or two to build a handful of sites in ASP.Net MVC with Entity Framework, so you're familiar with the basics. At that point you'd be marketable for a lot of current senior .Net positions. Experience with .Net is more relevant to most companies than MVC-specific experience. Add in your SQL Server skills for when Entity Framework doesn't cover exactly what you need and you can almost write your own ticket.
