无法在 C# bot 框架中集成 OpenXML (documentformat.openxml.*)，出现错误“Autofac.Core.DependencyResolutionException”

Question

为了优化 powerpoint(.pptx) 文件，我使用了 OpenXML SDK(DocumentFormat.OpenXML)，它可以作为控制台应用程序正常工作。 但是，由于需要在 bot 框架中实现相同的功能，我添加了所需的 nuget 包，即“DocumentFormat.OpenXml.*”。对新的呼唤 messageController 中的对话框在这一行抛出错误：

await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());

在我添加 nuget 包“DocumentFormat.OpenXml.*”之前，Bot 在模拟器中运行良好。但是，它会引发上述错误。找不到相关文章。

完整的方法代码：

public class MessagesController : ApiController
{

    public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
    {

        try
        {
            if (activity.GetActivityType() == ActivityTypes.Message)
            {
                await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
            }
            else
            {
                HandleSystemMessage(activity);
            }
        }
        catch (Exception ex)
        {
            activity.CreateReply(ex.Message);
        }
        var response = Request.CreateResponse(HttpStatusCode.OK);
        return response;
    }

对于所有一直在处理类似问题的人，解决方案是继续使用以下 OpenXml nuget 包：

DocumentFormat.OpenXml;

DocumentFormat.OpenXml.Presentation;

DocumentFormat.OpenXml.Spreadsheet;
