Microsoft.Composition 1.0.27 与 .NETCoreApp 不兼容，版本=v1.0

Question

在为新项目的发布进行编译时出现此错误。使用 .Net 4.52 作为一些旧包的主要框架（主要是 Paypal）

我使用框架中的“导入”部分阅读了很多其他帖子，但这对我解决这个问题没有帮助。

错误信息：

包 Microsoft.Composition 1.0.27 不兼容 netcoreapp1.0（.NETCoreApp，版本=v1.0）。

包 Microsoft.Composition 1.0.27 支持：portable-net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile259)

该消息准确地描述了问题。您的项目以 .Net Core 1.0 为目标，并且包与它不兼容。

发生这种情况是因为并非所有 .Net 平台和版本都兼容。例如 .Net Core 1.0 仅与 .Net Standard 1.6 兼容。这个page 显示了一个表格，其中包含不同 .Net 平台之间的兼容性。

在这种特定情况下，您的目标是 .Net Core 1.0，而包的目标是 4.5。如您在表中所见，这些不兼容。
