重现的步骤

我使用这篇official ASP.NET和this文章将我的ASP.NET Core 1.0应用升级到1.1。该应用程序编译正常，但当我使用F5运行应用程序时，我收到以下错误

错误：

HTTP Error 502.5 - Process Failure

Common causes of this issue:

The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port

进一步的技术细节

操作系统：Windows 10

Visual Studio版本：2015-Update 3（包含最新更新）

注意：

我的应用程序是在默认内置IIS Express上运行的开发机器（Windows 10）上。不涉及服务器或迁移到其他服务器。

您需要安装https://www.microsoft.com/net/download/core

的

import scala.collection.mutable

object CoOccurrence {

  val text = Seq("love, new, truck, present", "environment, save, trying, stop, destroying", "great, environment, save, money, animals, zoo, daughter, fun", "impressive, loved, speech, inspiration", "Happy Birthday, brother, years, old", "save, money, stop, spending", "new, haircut, love, check it out")

  def main(args: Array[String]) {
    val cooc = mutable.Map.empty[(String, String), Int]

    text.foreach { line =>
      val words = line.split(",").map(_.trim).sorted
      val n = words.length
      for {
        i <- 0 until n-1
        j <- (i + 1) until n
      } {
        val currentCount = cooc.getOrElseUpdate((words(i), words(j)), 0)
        cooc((words(i), words(j))) = currentCount + 1
      }
    }

    println(cooc)

  }
}

版本

Answer 2

你安装了1.1运行时吗？当您更新参考文献时，它不会自动安装它。

Answer 3

我发现同样的问题，但我的目标框架工作是 netcoreapp2.0 ，我通过使用自包含部署解决了它，而不是每个Microsoft文档的第三方依赖项。
