blazor-server-side - "TransformAppSettings"任务意外失败

Question

我有一个 .NET Core 3 Blazor(服务器端)应用程序，我最近将它从预览版 5 升级到了 .NET Core 3.0.1 预览版 6 版。当我在本地构建和运行它时，它工作正常；但是当尝试将其发布到文件系统文件夹(在框架相关模式下)时，它会引发此错误:

C:\Program Files\dotnet\sdk\3.0.100-preview6-012264\Sdks\Microsoft.NET.Sdk.Publish\targets\TransformTargets\Microsoft.NET.Sdk.Publish.TransformFiles.targets(192,5): Error MSB4018: The "TransformAppSettings" task failed unexpectedly. System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified. File name: 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'

at Microsoft.NET.Sdk.Publish.Tasks.AppSettingsTransform.UpdateDestinationConnectionStringEntries(String destinationAppSettingsFilePath, ITaskItem[] destinationConnectionStrings) at Microsoft.NET.Sdk.Publish.Tasks.TransformAppSettings.TransformAppSettingsInternal() at Microsoft.NET.Sdk.Publish.Tasks.TransformAppSettings.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.d__26.MoveNext()

或许值得一提的是，这个错误在预览版 5 版本中并没有发生。此外，我使用 Visual Studio Enterprise 2019 (Windows)。

到目前为止我尝试过的事情:(没有运气)

清洁/重建解决方案

重新安装 .NET Core 3 预览版 6 SDK

添加 Newtonsoft.Json通过 Nuget 打包

Answer 1

就我而言，我编辑发布配置并关闭数据库 -> 在运行时使用此连接。然后我可以在没有此错误的情况下发布，但是，我必须手动编辑 web.config 并进行以下更改。

modules="AspNetCorModuleV2"  had to become modules="AspNetCodeModule"

hostingModel="InProcess" had to become hostingModel="OutOfProcess" 

<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" /> had to become value="Production"

这些更改已经在我自己的目录 web.config 中，但它们似乎不再在发布中传播。
