How to use libgit2sharp from fsharp

this is on Server 2016 with net471 which should behave like windows 10.

So i am dowloading via nuget LibGit2Sharp prerelease in my paket.dependencies, which resolves to

LibGit2Sharp (0.26.0-preview-0027)
LibGit2Sharp.NativeBinaries (1.0.226) - restriction: >= netstandard2.0

in a fresh fsi (using ionide ) i can reference LibGit2Sharp.dll and open the LibGit2Sharp namespace, but instantiating a Repository throws following error:

Microsoft (R) F# Interactive version 10.1.0 for F# 4.1

> #r "../../packages/play/LibGit2Sharp/lib/netstandard2.0/LibGit2Sharp.dll";;

--> Referenced 'd:\scripts2dev\libwba\src\play\../../packages/play/LibGit2Sharp/lib/netstandard2.0/LibGit2Sharp.dll' (file may be locked by F# Interactive process)

> open LibGit2Sharp;;
> let  repo = new Repository("path\to\repo.git");;

Stopped due to error

And I can't reference the dll from LibGit2Sharp.NativeBinaries, because it throws

> #r @"../..\packages\play\LibGit2Sharp.NativeBinaries\runtimes\win-x64\native\git2-b0d9952.dll";;

LibGit2Sharp.fsx(7,1): error FS0229: Error opening binary file 'd:\scripts2dev\libwba\src\play\../..\packages\play\LibGit2Sharp.NativeBinaries\runtimes\win-x64\native\git2-b0d9952.dll': d:\scripts2dev\libwba\packages\play\LibGit2Sharp.NativeBinaries\runtimes\win-x64\native\git2-b0d9952.dll: bad cli header, rva 0

What am I missing? How can I use the compiled libraries ?
