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

Question

在新項目上進行發布時遇到此錯誤。 使用.Net 4.52作為某些較舊軟件包（主要是Paypal）的主要框架

我已經閱讀了框架中使用“導入”部分的許多其他文章，但這對解決這個問題沒有幫助。

錯誤信息：

軟件包Microsoft.Composition 1.0.27與netcoreapp1.0（.NETCoreApp，Version = v1.0）不兼容。

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

Answer 2

該消息准確地描述了問題。 您的項目針對的是.Net Core 1.0，並且該軟件包與之不兼容。

發生這種情況是因為並非所有.Net平台和版本都兼容。 例如，.Net Core 1.0僅與.Net Standard 1.6兼容。 本頁顯示具有不同.Net平台之間兼容性的表。

在這種情況下，您的目標是.Net Core 1.0，而軟件包的目標是4.5。 如表中所示，它們不兼容。
