描述
Reproduction steps
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");;
System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'git2-b0d9952': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

at <StartupCode$FSI_0003>.$FSI_0003.main@() in d:\scripts2dev\libwba\src\play\LibGit2Sharp.fsx:line 4
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
LibGit2Sharp.fsx(7,1): error FS3160: Problem reading assembly 'd:\scripts2dev\libwba\src\play\../..\packages\play\LibGit2Sharp.NativeBinaries\runtimes\win-x64\native\git2-b0d9952.dll': Processing of a script fragment has stopped because an exception has been raised
What am I missing? How can I use the compiled libraries ?
Expected behavior
It is possible to reference and use LibGit2Sharp in fsi
Actual behavior
see above errors
Version of LibGit2Sharp (release number or SHA1)
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
Operating system(s) tested; .NET runtime tested
this is on Server 2016 with net471 which should behave like windows 10.

调研方向
在 Server 2016 上使用 net471 和指定软件包版本中的 LibGit2Sharp.dll,在全新的 F# Interactive 会话中重现该问题。比较成功的程序集引用、失败的 Repository 构造,以及对本机 git2-b0d9952.dll 的引用尝试。完成的标准是 FSI 可以引用并使用 LibGit2Sharp,且不会出现本机库加载错误。
