LibGit2Sharp TypeInitializationException in Web project - asp.net

Question

I use VS 2012. My solution contains one web-site project and one project library .
I installed the nuget package on my project Library only.
In my Library I created a simple class "GitRepo" to test git access. In the constructor, I want to access the repository :
public GitRepo(string repoPathName)
{
m_Repo = new Repository(repoPathName);
}
In the code behind of my web page, I try to instantiate a GitRepo object :
GitRepo repo = new GitRepo(repoPathName);
And I get the TypeInitializationException with no more details. And yes, dll and native libraries structure seems correct in the file tree (installed by nuget package).
I have a simple console program's solution where I added my previous library (add existing object). In the "main" function, I instantiate a "GitRepo" object... and it works fine.
Some help would be greatly appreciated.
Here the full exception :

nulltoken, thank you for your help.I've started a new console project and added my library located in another folder. When I instanciate my "GitRepo" object (from my library) there's no exception. So I checked the directory tree of the solution and I saw that LibGit2Sharp.dll and NativeBinaries folder were added automatically under bin/debug of the program's folder.
Thus I checked the bin folder of my web project and I saw there was not the "NativeBinaries" folder. I add it manually and now there's no more exception.
