F# is just a better language. Simpler, more concise, more readable with stronger type safety. I will never go back to writing C# as I'm finding it too frustrating at times and unproductive.

I have been programming in F# full time for the past 7 years and I hope that rumours of its death are greatly exaggerated. Perhaps this comes from a point of view that if something is not growing 10x each year is dead?

It's not a JavaScript framework that has an average lifespan of a couple of years. It's a fully featured, complete, very productive language that makes programmers life easier and more enjoyable.

Smart constructor technique works well with 'parse, don't validate' approach [0]. You can push type construction to the boundries of your system so that you can work on a domain code with more precise types. It's not always so rosy however as too much types can become a burden.

This works great with "makes illegal states unrepresentable" approach. It helps to reduce a need for boring unit tests and lets you focus more on expressing domain in code directly.
