Native?

[dzmitry-lahoda]

F# supports expression with pointers, same will not compile in C#:

          let x = NativePtr.ofNativeInt<int>(nativeint(0))
          let z = <@ x @>

Are you are aware of making C# expressions to support pointers?

@dzmitry-lahoda no I am not. But maybe you can use refs? (aka managed pointer).

Is that a "computation expression" you are showing?

[dzmitry-lahoda]

As I know C# does not compiles ref into LINQ Expression. But LINQ Expression supports some of these via direct construction of AST via method calls. And LINQ Expression does not supports new C# 7+ ref features. I have skimmed MS work prototypes about future of LINQ Expression and have not seen work on this.

LINQ Expression compiled from C# via Expression<Func> is same as F# https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/code-quotations . But F# has wider and better support for more stuff with less boilerplate. May be mixes well with computation expression.

TensorFlow is built for every where, native wrapped into C#, pure JS. So is there any niche for alternative?

Meanwhile, is there niche to run algorithms on real or mmaped memory over dozens of GB. Algorithms may be run directly or quoted into optimized for GPU/SIMD, hybrid. So that substrate can be made as step of ladder for higher level stuff DLS in pure .NET, up to declarative graphs like in TensorFlow, or used directly to analyze tons of data with raw power.
