我的构建成功构建 + 部署在 Azure 集群中。 VSTS 构建任务

我没有代码更改。我比较了工作和不工作的构建工件。我的 MyCompany.MyService.Api.deps.json 文件中有新条目：

在过去的几个月里，我成功地构建和部署了。然而在过去的 5 天里，从 VSTS 构建构建的代码无法部署到集群。我的 API 服务无法启动，并且出现以下错误。请建议我如何调试。代码在我的本地集群中成功部署和启动。

这是一个与 asp.net core 2.1 相关的已知错误。几周前我们遇到了同样的问题。

核心 2.1 的安装存在一些相互冲突的依赖关系，会影响其他 dot net 版本。VSTS 构建环境或 SF 可能已升级到核心 2.1 并影响了您的旧构建。

你可以：

降级到 2.0：在我们的案例中，我们有一些针对核心 2.1 的服务以及一些 1.1 和 2.0，我们将所有服务降级到核心 2.0，问题得到了解决。

或者，

AddMvc()您可以在您的 api行之前添加以下代码来修复依赖关系问题。

看起来像这样：

var manager = new ApplicationPartManager();
manager.ApplicationParts.Add(new AssemblyPart(typeof(Startup).Assembly));
manager.ApplicationParts.Add(new AssemblyPart(typeof(Project1.Project1Type).Assembly));

services.AddSingleton(manager);
services.AddMvc();

或者，

将global.json文件添加到您的解决方案。

像这样：

{
  "sdk": {
    "version": "2.1.200"
  }
}
