Question

我正在尝试让Firebird Embedded在简单的.NET Core（2.1）控制台应用程序场景中工作。

我的项目文件如下：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FirebirdSql.Data.FirebirdClient" Version="6.4.0" />
  </ItemGroup>

</Project>

和Program.cs像这样：

using System;
using System.IO;
using FirebirdSql.Data.FirebirdClient;

namespace Playground
{
    class Program
    {
        static void Main(string[] args)
        {
            var workingDir = Directory.GetCurrentDirectory();
            var dbPath = Path.Combine(workingDir, "Database.fdb");

            var connString = 
                new FbConnectionStringBuilder
                {
                    ClientLibrary = "libfbclient.dylib",
                    ServerType = FbServerType.Embedded,
                    UserID = "sysdba",
                    Database = dbPath
                }
                .ToString();

            Console.WriteLine(connString);

            FbConnection.CreateDatabase(connString, false);

            var sql =
                @"
                CREATE TABLE my_table (
                    id int NOT NULL PRIMARY KEY,
                    name varchar(20) NOT NULL
                );
                ";

            using (var conn = new FbConnection(connString))
            using (var cmd = new FbCommand(sql, conn))
            {
                conn.Open();
                cmd.ExecuteNonQuery();
            }
        }
    }
}

构建项目后（仅用dotnet build），我将以下文件从Mac的二进制软件包（Firebird-3.0.4-33054-lipo-x86_64.pkg）复制到输出目录（./bin/Debug/netcoreapp2.1）：

libfbclient.dylib
libib_util.dylib
libicudata.dylib
libicui18n.dylib
libicuuc.dylib
plugins (directory)
    libEngine12.dylib

运行应用程序（dotnet MyApp.dll）时出现异常：

Unhandled Exception: FirebirdSql.Data.FirebirdClient.FbException: Unable to complete network request to host "localhost".

过去15年来，尽管仅在Windows上，我已经在许多场景（网络服务器，嵌入式）和不同技术（Delphi，.NET，.NET Core）中成功使用了Firebird。

有人能协助解决这个问题或将我指向可以自己进行RTFM解决的地方吗？
