When referencing this package in Functions V2, the following exception prevents the host from starting up:

DurableTask.SqlServer.AzureFunctions: Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=3.1.26.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified. System.Private.CoreLib: Could not load the specified file.

Although the Functions V2 host is no longer supported, there are still many V2 apps in production which would be impacted if this package were included in V2 or V3 extension bundles.

In order to be considered for V2 or V3 extension bundles (which are the only production extension bundles at the time of writing), the host must be able to start when referencing the DurableTask.SqlServer.AzureFunctions package.
