F# is definitely a great language. It would be amazing if the interop with Entity Framework was improved, too, with regards to code-first development. Not having a nice and easy way to define virtual properties on records and classes is something I miss a lot:

Not sure how difficult it would be to implement a [CliVirtual] attribute (https://fslang.uservoice.com/forums/245727-f-language/sugges...), but that would definitely help and make the EF-models more readable.

But in general, F# is great. I hope more people will use it.
