应用部署失败

Question

我开始在 Google Cloud 上使用 App Engine。我从 Google 下载了示例应用程序并运行它，它运行良好。当我在 .Net Core Razor Pages 的 VS2017 中创建一个新项目时。我在我的电脑上运行它没有任何问题。但是，当我将其部署到云时，它失败了。我访问了两者的日志。第一个日志来自示例应用程序。第二个日志是我自己的项目。我在日志中看不到任何错误或任何不同。我错过了什么吗？

Answer 1

更新

自 2018 年 4 月 10 日起，Google Cloud App Engine .Net Core 运行时支持 .Net Core 2.0.6。

原始答案 此问题可能是由于使用 MS VS 2017 模板创建的 te 项目使用的 .Net Core 版本与我们目前在 App Engine 中支持的 .Net Core 版本不匹配。您可以跟踪问题here。

我可以提供两个临时解决方案：

1. 编辑 *.csproj 文件并将 .Net Core 版本更改为 2.0.0，在 VS 上重新加载项目并部署。如下：

<ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
</ItemGroup>

1. 使用安装了Google Cloud Tools for Visual Studio 后可用的 Google Cloud 模板创建您的项目，Google Cloud Tools for Visual Studio 将使用 App Engine 支持的 .Net Core 版本。这里：
