。NET Core SDK新项目类型-无法调试COM加载项？

Question

我最近在一个旧项目上升级到.NET Framework 4.8，并且认为我发现了Visual Studio 2019调试器和/或新的.NET Core SDK项目类型的局限。

下面是csproj的前后：

Excel-DNA目前不支持新的SDK样式的项目，我们正在努力添加对即将发布的Excel-DNA版本的支持。

您可以跟踪以下问题以获取有关该方面进展的通知：

• Update ExcelDna.AddIn NuGet Package to support the new PackageReference format #193
• Update ExcelDna.Integration NuGet Package to support the new PackageReference format #188
• ExcelDna.AddIn NuGet package installation fails as a PackageReference #138
