Unable to reference native library

[mzorec]

Flubu is having problem loading LibGit2Sharp.NativeBinaries package(https://github.com/libgit2/libgit2sharp.nativebinaries) which contains compiled versions of the libgit2 native library. Well it has problem loading any native library not only from libgit2.

ScriptError:CS0009: Metadata file 'D:_GitFlubu\FlubuSample\flubucore-versionize-sample\BuildScript\FlubuLib\git2-106a5f2.dll' could not be opened -- PE image doesn't contain managed metadata.

@sreejith-ms I have found out that native library has to be in same directory as the library that has dependecy on it. I have made pull request to your sample script repository https://github.com/sreejith-ms/flubucore-versionize-sample where I have put libgit2sharp.dll and libgit2sharp.native.dll to the same lib folder and add reference to libgit2sharp.dll in project file.

I am still not sure how to fix this when adding libgit2sharp with nuget package as libraries are not in the same nuget folder and also both libraries must not be added as references in project file or more exactly they must not be referenced when compiling the script only libgit2sharp.dll has to be referenced otherwise this error occurs PE image doesn't contain managed metadata.

Probably all nuget references should be copied to buildscript bin folder but that means longer startup when the script has to be compiled / recompiled.

@mzorec I have faced a DLL not found issue when I run BuildScript in a CI system. But it is fixed when I updated libgit2sharp to the preview version as per this issue.
So the native library issue only occurring to libgit2sharp or do you able to test any other packages?

[mzorec]

I haven't tested it on other packages. I will try with one other package when I have time. It might be libgit2sharp specific issue.

Looks like libgit2sharp specific issue.
