错误 502.5 - 进程失败 ASP.NET Core 1.1

Question

我在部署我的 ASP.NET 核心网络应用程序时遇到此错误。我做了以下事情：

启用 Web 服务器 (IIS) 角色并建立角色服务。
安装 .NET Core Windows 服务器托管捆绑包 v2.0.3
重启系统或执行net stop was /y然后net start w3svc

这是我的 csproj 文件：

我在事件查看器中收到此错误：

Application 'MACHINE/WEBROOT/APPHOST/WWW.MYWEBAPP.COM' with physical root 'C:\inetpub\www.mywebapp.com\' failed to start process with commandline 'dotnet .\mywebapplication.dll', ErrorCode = '0x80004005 : 80008083.

Answer 1

您很可能缺少 Visual C++ 2015 运行时（可用 here）。托管包会在安装期间尝试下载并安装它，但如果出现网络问题或服务器无法连接到外部（在企业环境中很常见），则会失败，您需要使用可重新分发。

我不记得我上次遇到这个问题时是否需要它，但你可能想在之后再次重启你的服务器，以防万一。

编辑

如果您仍然遇到问题，请通过以下方式从命令行尝试运行您的应用：

dotnet MyApp.dll

这会让您看到在启动时引发的任何异常。

如果您收到如下错误：

It was not possible to find any compatible framework version ...

确保您拥有应用程序所针对的 ASP.NET 核心版本的特定运行时。目前，它是 2.0.3（适用于所有 2.X 应用）或 LTS 1.1.5（适用于所有 1.X 应用）。您可以找到最新的运行时 here.

Answer 2

我发现了同样的问题，但我的目标框架工作是 netcoreapp2.0 并且我根据以下 Microsoft 文档使用没有第三方依赖项的独立部署解决了这个问题。我也使用了目标框架netcoreapp1.0，它可以使用相同的方法解决。
