.Netstandard2.0 Migration

[Arastookhajehee]

Summary

The updates include Machina migrating from .NET Framework 4.6.1 to the SDK-style project targeting .NET Standard 2.0, and updates all sample and test projects to use .NET Framework 4.8.1. It also introduces a new utility function for JSON conversion that uses Newtonsoft.Json instead of the depricated json serializer.

First migraiton step

The first migration was from .NF46 to NF481 to make it compatible with Microsoft's migration automation tools.

Dependency and reference management:

• Switched from direct assembly references to PackageReference for dependencies like Microsoft.CSharp, Newtonsoft.Json, and System.Data.DataSetExtensions in Machina.csproj.
• Moved ABB and RobotStudio DLL references to a dedicated item group at the bottom of the project file for clarity and to avoid breaking dependent projects.

Limitations

Direct Migration to .Net8.0 is impossible due to these ABB dll files that require .NetFramework runtimes.

Tests

The code is tested in Rhino 8 with .Net8.0 Runtime and the new Machina-Bridge.
Tests were successful and without noticable difference from the .NetFramework4.6.0 version.
Tests were conducted on a UR10e robot and ABB robot studio simulation environments.

Pull request overview

This PR migrates the Machina library from .NET Framework 4.6.1 to .NET Standard 2.0, while updating all test projects to .NET Framework 4.8.1. The migration enables broader compatibility with both .NET Framework and .NET Core/.NET applications, while maintaining support for ABB RobotStudio DLLs that require .NET Framework runtimes.

Changes:

• Migrated main Machina project to SDK-style project targeting .NET Standard 2.0
• Updated all test projects from .NET Framework 4.6.1 to 4.8.1
• Introduced Newtonsoft.Json dependency and added ToNullableDoubles utility function for JSON conversion
• Reorganized assembly references and removed auto-generated Properties files

The comment states "This is replacement for the NullableDoublesFromObjects function in .NetStandard and above" but this is confusing. The new ToNullableDoubles function actually works alongside NullableDoublesFromObjects (it calls it internally). The comment should clarify that this provides a convenient wrapper for JSON parsing scenarios in .NET Standard 2.0, rather than saying it's a replacement.

Suggested change

	/// This is replacement for the NullableDoublesFromObjects function in .NetStandard and above.
	/// Provides a convenient wrapper around NullableDoublesFromObjects for JSON parsing scenarios
	/// (for example when working with JSON in .NET Standard 2.0), rather than replacing it.
