Question

我的Azure WebJob始终以退出代码-2146232576失败。有谁知道退出代码与什么有关？

我正在尝试按计划运行它，我的源代码可以在这里找到：

相关代码：

Program.cs的

using Microsoft.Azure.WebJobs;

namespace TrakIMDB250.Scraper
{
    class Program
    {
        static void Main(string[] args)
        {
            var config = new JobHostConfiguration();    
            var host = new JobHost(config);    
            host.Call(typeof(Functions).GetMethod("ScrapeIMDB250"));
        }
    }
}

我的问题是我飞得太靠近太阳试图运行.NET 4.6。

将解决方案降级为4.5.2并且运行良好：）

注意：一旦4.6正式支持，这个解决方案就会变得无关紧要。

截至8/3/2018，此兼容性问题仍然存在问题。 .NET 4.7.2产生同样的错误，但降级到4.7.1会起作用。
