Question

我正在尝试修复我的问题，即恢复具有自定义包源的.net core 2.0 webapi的nuget包。

基本上，当包含nuget.config时，任何微软软件包都无法安装，因为它似乎忽略了我的nuget引用。

我找到了一个解决方法，即删除我的自定义nuget.config，让构建失败，一旦失败，它将从nuget.org下载正确的东西，然后通过添加自定义文件，它将从磁盘恢复那些微软软件包然后到达以获取我的自定义nuget软件包。

我的nuget Package配置如下所示：

    <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="ASPNET Team" value="https://dotnet.myget.org/F/aspnetcore-ci-dev/api/v3/index.json" />
    <add key="OTL" value="https://www.myget.org/F/{redacted}/api/v3/index.json" />
  </packageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
  <disabledPackageSources />
</configuration>

Kudu的错误是：

直接从Kudu控制台执行dotnet恢复会产生相同的结果。我从我的开发机器中取出了NuGet.config，我知道它已经成功恢复了微软软件包和自定义软件包，并试图使用它并且它仍然失败。

我开始认为它的出站端口阻止了azure中的防火墙事件，但是在webapp上对出站防火墙或代理进行了一些谷歌搜索并不富有成效。

因此，在研究和处理Kudu团队和Nuget团队之后，我们发现Azure WebApps在基本和自由层中的线程数量有限，并且当nuget恢复发生时，它以并行异步方式执行，并且它达到了线程限制并失败。

要修复，您必须在dotnet还原上使用--disable-parallel部署自定义部署脚本。
