HTTP 错误 502.5 - 将 ASP.NET Core 1.1 复制到另一台机器后进程失败

Question

我按照官方 ASP.NET 网站上的程序将我的 ASP.NET 核心应用程序从 1.0 升级到 1.1。该应用程序在 Windows 10（从 win 7 升级）的原始位置上运行良好。但是当我在另一台也安装了最新的 VS2015-Update3 并安装了 NET Core 1.0.1 tools Preview 2 的机器 (Win 7) 上复制该应用程序时，该应用程序编译正常但出现以下错误：HTTP Error 502.5 - Process Failure

此外，事件日志显示如下：

Failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -p "C:\Program Files\dotnet\dotnet.exe" -a "C:\DotNET2015\ABCTest\src\ABCTest\bin\Debug\netcoreapp1.1\ABCTest.dll" -wd "C:\DotNET2015\ABCTest\src\ABCTest" -wbe Global\Build500340c7-6e16-4a08-b314-ff5fd51b1dcb -lse Global\Launchb628508b-6e25-455f-9afa-6092434506ed', ErrorCode = '0x80004005'.

Answer 1

我在 Visual Studio 中更新 NuGet 包时遇到了同样的问题。 就我而言，解决方案是降级软件包： Microsoft.AspNetCore.Server.Kestrel 从 1.1.0 到 1.0.1 Microsoft.NETCore.App 从 1.1.0 到 1.0.1

..然后一切又恢复正常了。

Answer 2

您需要在将应用程序复制到的计算机上安装 .NET Core 1.1 运行时。你安装的是1.0.1.
