[Feat]: Support .NET Standard 2.0

[bloomer-joe]

Version

1.6.7

Environment that reproduces the issue

Our dev team is being asked to support this for both .NET 8.0 MAUI and a .NET 4.8.1 API backend.

Use case description

Users stuck with other .NET frameworks want to use this package out of the box.

Proposed solution

Rename <TargetFramework> to <TargetFrameworks> in .csproj files and modify from "net5.0" to "net5.0;netstandard2.0".

Alternative solutions

No response
