- if you are already rewriting, that's a good start... - i'd use Typescript as a starting point - NodeJS has a ton of community around it. How I would make the decision for myself: - what frameworks / languages are you personally comfortable supporting, and would be able to jump in and fix if it came down to it. - you will find devs for any language, and will find many devs willing to learn a language and framework for a great job, so are you willing to take a hit with .net if people you will interview don't really know .net yet (thus a learning curve). - if you already have a large pool of potential consulting companies who can work with nodejs, use that. for emphasis - what frameworks / languages are you personally comfortable supporting, and would be able to jump in and fix if it came down to it. Personally I am not comfortable with .net and would have a large learning curve trying to support anything. So I would not choose .net for myself if I was deciding. Though... web frameworks are all more or less doing the same thing, so its not like you'll be starting at square zero.
