AWS Lambda - Unable to load library

Comece pela reprodução na issue, especialmente em Function.cs e seu FunctionHandler, usando o deployment do Amazon.Lambda.Tools e o pacote LibGit2Sharp 0.27.0-preview-0034. Rastreie a falha por meio de NativeMethods.InitializeNativeLibrary e compare o ambiente Lambda implantado com a DllNotFoundException relatada. O trabalho estará concluído quando a função implantada puder construir LibGit2Sharp.Repository e ser invocada com sucesso sem o erro da biblioteca nativa.

Reproduction steps

dotnet tool install -g Amazon.Lambda.Tools
dotnet new --install Amazon.Lambda.Templates
dotnet new lambda.EmptyFunction --name LambdaGit
cd LambdaGit/src/LambdaGit
dotnet add package LibGit2Sharp --version 0.27.0-preview-0034
--- add "new LibGit2Sharp.Repository();" in "FunctionHandler" function in "Function.cs"
dotnet lambda deploy-function LambdaGit --function-role LambdaGitRole
dotnet lambda invoke-function LambdaGit --payload "LambdaOK"

Version of LibGit2Sharp (release number or SHA1)

I tested all 84 available versions of GitLib2Sharp on Nuget. None of them worked.

Operating system(s) tested; .NET runtime tested

Amazon Linux 2
.NET Platform: 3.1

I analyzed several related issues in the GitLib2Sharp, aws-lambda-dotnet and Docker repositories but I was unable to solve this problem.

Please help me.
