BizTalk 2020 添加特定NuGet包后AddBizTalkHiddenReferences报错生成失败如何解决

复现步骤 #

1. 运行环境栈：Windows 10、Visual Studio 2019 专业版、BizTalk Server 2020 开发者版 CU1
2. 在Visual Studio中新建BizTalk Server项目
3. 打开NuGet包管理器，添加对应NuGet包，可选类别如下：
   • 已知会导致生成失败的包版本：autofac 6.0/6.1/6.2、nodatime 3.0.5、Azure.Storage.Blobs 12.9.1
   • 已知不会导致生成失败的包版本：autofac 5.2、其余多数测试过的NuGet包
4. 按F6执行生成操作，或直接运行msbuild命令

经测试验证：若NuGet包的依赖项直接包含.NET Framework版本变体，生成可正常完成；若包仅标注.NET Standard和.NET 5作为依赖项，则会触发生成失败问题。

实际报错信息：

问题复现压缩包可在公开的Autofac项目Issue记录中获取，最初排查时误以为是autofac专属问题，实际为通用问题。

此前使用旧环境栈（Windows Server 2016、Visual Studio 2015、BizTalk 2016）未出现该问题，该环境下BizTalk项目中使用autofac 6.1完全正常。

目前判断该问题为BizTalk本身的Bug，但暂未找到向微软反馈问题的官方渠道，咨询是否有对应的临时规避方案或官方修复补丁？
