非托管导出:无法编译程序集

我想创建一个可以从非托管代码(Delphi5)访问的.NET程序集。

我找到了 Unmanaged Exports 并遵循了这些步骤,但我甚至无法成功地编译基本示例:

using RGiesecke.DllExport;

namespace DelphiNET
{
    public class Class1
    {
        [DllExport("add")]
        public static int Add(int left, int right)
        {
            return left + right;
        }
    }
}

DelphiNET.csproj 项目文件:

...
<ItemGroup>
  <Compile Include="Class1.cs" />
  <Compile Include="DllExport\DllExportAttribute.cs" />
  <Compile Include="Properties\AssemblyInfo.cs" />
</ItemGroup>
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Import Project="DllExport\RGiesecke.DllExport.targets" />
...

错误如下:
