Fody is only supported on MSBuild 16 and above. Current version: 15
问题 Visual Studio 2017 let me know there was an upgrade to Fody version 5 this morning. I accepted and did a NuGet package update of both Fody and PropertyChanged.Fody. Now, my project/solution will no longer build. The error is: "Fody is only supported on MSBuild 16 and above. Current version: 15." I tried uninstalling, shutting down VS, and reinstalling to no avail. 回答1: Please downgrade Fody to version 4.2.1. 回答2: Upgrade to Visual Studio 2019 https://visualstudio.microsoft.com/downloads/ 回答3:
