That's because F# 1.0 was bascially a more powerful language than C# 10.0 (C# still doesn't have proper pattern matching for example, or discriminated unions)

For features added see https://en.wikipedia.org/wiki/F_Sharp_(programming_language)

Named union type fields Extensions to array slicing Type inference enhancements Printf on unitized values Extension property initializers Non-null provided types Primary constructors as functions Static parameters for provided methods Printf interpolation Extended #if grammar Support for 'fixed' Tailcall attribute Multiple interface instantiations Optional type args Params dictionaries Struct tuples which inter-operate with C# tuples Struct annotations for Records Struct annotations for Single-case Discriminated Unions Underscores in numeric literals Caller info argument attributes Result type and some basic Result functions Mutually referential types and modules within the same file Implicit "Module" syntax on modules with shared name as type Byref returns, supporting consuming C# ref-returning methods Error message improvements

All those features mean nothing to seasoned .NET developers when you can't use the language natively on Microsofts primary application platform.

You can gripe about your fav UI stack not being supported just the way you want (you don't seem to have any other complaints), but your claim the language is not improving is wrong.

.NET Native and UWP are not just UI,
