Unable to load DLL 'git2'

Hi All,

I know there are a number of similar issues listed, but non quite fit my scenario.

I have a system (that I cant change) that stores code and dlls (binary blob) in a database. The data is extracted and a VS Solution is generated. As such I do not have the ability to use NuGet or to force the git2-4aecb64.dll into the specific folders required for it to work.
Additionally the git2.dll is renamed (also out of my control) with a UID on the end.
eg. git2-4aecb64_Server_c8l_S0Kakc7Do5PhhDGPhxoObuMgSRw2detcnbwdOuQ.dll

So, based on other incidents raised, I understandably get the following error when the git-xxx.dll is included in the root folder next to LibGit2Sharp.dll

System.Web.Services.Protocols.SoapException: Server was unable to process request.
---> System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception. --->
System.DllNotFoundException: Unable to load DLL 'git2-4aecb64': The specified module could not be found. (Exception from HRESULT: 0x8007007E)at LibGit2Sharp.Core.NativeMethods.git_libgit2_init()at LibGit2Sharp.Core.NativeMethods.LibraryLifetimeObject..ctor()at LibGit2Sharp.Core.NativeMethods..cctor()
--- End of inner exception stack trace ---

Does anyone have any suggestions for resolving this?

Possibly a config item I can pass to LibGit2Sharp that would take a relative path to the git2.dll?

Or could I build a combined DLL?

Reproduction steps

1. Create new VS 2017 c# console app
2. Manually add Reference to LibGit2Sharp.dll and then copy git2-4aecb64.dll to the bin folder
3. Try to Clone a Repository using below code

var cloneOptions = new CloneOptions { BranchName = "master", Checkout = true };
cloneOptions.CredentialsProvider = (_url, _user, _cred) => new UsernamePasswordCredentials { Username = username, Password = pass };
string localFolder = @"C:\Repos\test"; 
var cloneResult = LibGit2Sharp.Repository.Clone(url, localFolder, cloneOptions);

Expected behavior

Repository is cloned

Actual behavior

Exception is raised
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'git2-4aecb64': The specified module could not be found.

Version of LibGit2Sharp (release number or SHA1)

Versions pulled from NuGet package
LibGit2Sharp - version="0.25.4"
LibGit2Sharp.NativeBinaries - version="1.0.252"

Operating system(s) tested; .NET runtime tested

Windows 10 with .Net 4.7

Thanks,

Parti dall’inizializzazione di NativeMethods mostrata nello stack trace e riproduci la configurazione manuale di VS 2017 con la git2 DLL rinominata. Una risoluzione utile stabilirebbe se LibGit2Sharp supporta il caricamento di quel binario rinominato esternamente oppure chiarirebbe la disposizione di distribuzione supportata, quindi verificherebbe che la chiamata a Clone non generi più DllNotFoundException.
