Description

The project currently targets:

<TargetFramework>netstandard2.1</TargetFramework>

While this works fine for modern .NET (Core 3.0+, .NET 5+, .NET 6+, etc.), it prevents consumers using .NET Framework 4.x or .NET Standard 2.0–only environments from referencing the library.

Problem

• netstandard2.1 is not supported by .NET Framework 4.8 or earlier.
• This limits compatibility for consumers that cannot yet upgrade to .NET 5+.
• We lose the flexibility to support a broader range of projects (e.g., older class libraries, plugins, legacy integrations).

Suggested Solution

Switch to multi-targeting to support both legacy and modern environments:

<TargetFrameworks>netstandard2.0;net8.0</TargetFrameworks>

This provides:

• ✅ Backward compatibility with .NET Framework via netstandard2.0
• 🚀 Access to modern APIs for .NET 6+/8.0 consumers
• 💪 Future-proofing without sacrificing reach

Additional Notes

• If any dependencies require netstandard2.1 or later, those can be conditionally included only for net8.0.
• CI/CD pipelines might need to be updated to test against both frameworks.
