IConfigurationSection does not contain a definition for Get

During maintenance I needed to upgrade some NuGet dependencies, one of them been Microsoft.Extensions.Configuration.Abstractions which was upgraded from 3.1.10 to 7.0.0. Which caused the following error

‘IConfigurationSection’ does not contain a definition for ‘Get’ and no accessible extension method ‘Get’ accepting a first argument of type ‘IConfigurationSection’ could be found (are you missing a using directive or an assembly reference?)

This method actually lives in the Microsoft.Extensions.Configuration.Binder assembly which was impacted by the Package reference changes affecting some NuGet packages: https://learn.microsoft.com/en-us/dotnet/core/compatibility/aspnet-core/5.0/extensions-package-reference-changes which recommends the following action.

Consumers of the affected packages should add a direct dependency on the removed package dependency in their project if APIs from removed package dependency are used. The following table lists the affected packages and the corresponding changes. Microsoft.Extensions.Configuration.Binder

So all we need to do to resolve the issue is jump back into NuGet and add a reference to Microsoft.Extensions.Configuration.Binder in our project directly as we’re using an API from it.
