Runtime: COREHOST_TRACE 应该记录 AssemblyLoadContext

背景
在 Windows 上，我正在与 .NET Core 全局工具集成，该工具又通过命令行参数assembly="c:\source\bin\Debug\netstandard2.0\JohnZabroski.Database.dll"加载程序集。 JohnZabroski.Database.dll传递地引用System.Data.SqlClient 。

问题
使用COREHOST_TRACE=1 ，我当前的 stderr 如下所示：

!!! Could not load file or assembly 'System.Data.SqlClient, Version=4.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621)
!!! +- Could not load file or assembly 'System.Data.SqlClient, Version=4.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

在尝试解决为什么找不到或找不到我的组装时，我发现以下博客文章相当令人生畏： https ://mattwarren.org/2016/07/04/How-the-dotnet-CLI-tooling-runs-your

我发现 .NET 4.6 中的 Assembly Fusion Log Viewer 工具更容易获得用户体验。 见： https ://github.com/dotnet/coreclr/issues/10379
