ASP.Net Core 3.1 發布錯誤 Error NU1605 解決方案

編譯都OK，發布就報錯，錯誤提示檢測到程序包降級，排查發現都是來自於 BofSoft.Data 項目引用的包 MySql.Data

/*
Error Detected package downgrade: System.Threading from 4.3.0 to 4.0.11. Reference the package directly from the project to select a different version.

在 BofSoft.Data 項目文件中指定所有出問題包的版本

<ItemGroup>
    <PackageReference Include="Dapper" Version="2.0.35" />
    <PackageReference Include="MySql.Data" Version="8.0.20" />
    <!--
    發布項目時出現如下錯誤：
    Error NU1605: Detected package downgrade: System.IO.FileSystem.Primitives from 4.3.0 to 4.0.1. Reference the package directly from the project to select a different version.
    檢測到包降級，原因是 MySql.Data 中引用的包版本與 .Net Core 3.1 中的不一致，因此在下面統一指定包的版本
    -->
    <PackageReference Include="System.Diagnostics.Debug" Version="4.3.0" PrivateAssets="all" />

再次發布成功
