im使用docker构建应用程序在aspnet核心中，无论是在调试模式下对iis还是docker都适用，但是当我想在发布模式下构建docker映像时，尝试从错误的源下载nuget后会失败。

未找到的螺母应从本地软件包服务器装入。 我还发现，当我将Container.targets中的容器开发模式更改为始终快速时，它可以正常工作。
<PropertyGroup Condition="'$(ContainerDevelopmentMode)' == ''">
<ContainerDevelopmentMode Condition="'$(Configuration)' == 'Debug'">Fast</ContainerDevelopmentMode>
<ContainerDevelopmentMode Condition="'$(ContainerDevelopmentMode)' == ''">Regular</ContainerDevelopmentMode>
</PropertyGroup>
所以我的问题是我应该使用“常规”开发模式还是有人针对此问题有更正确的解决方案？谢谢
