Is there something like Kirby or Jekyll for .NET?

I am considering CMS solutions for my company (because I am sick of coding press releases and other things people have to do themselves). I came across Kirby and Jekyll which generate sites without a database that can be edited with standard markdown. This is very appealing to me and I think it might be a great solution for our team, but the problem is that we are working in .NET and it is very unlikely that we will change anytime soon as it will require a major restructuring. and our resource is currently linked to other things.

I'm just wondering if there are tradeoffs out there for .NET?
