NuGet 错误 NU5042

  • 项目 
`project.json` pack is disabled in the current NuGet version, and will be permanently removed in a future version.
Please consider migrating 'MyProject' to `PackageReference` and using the pack targets.
You can set the 'NUGET_ENABLE_LEGACY_PROJECT_JSON_PACK' environment variable to 'true' to temporarily reenable this functionality.

问题

不支持针对 project.json 项目的 NuGet.exe pack。

解决方案

将项目迁移到 PackageReference，并改用 pack 目标。
