Reloaded.SolverFoundation 1.0.6

Microsoft Solver Foundation Express Edition for NET. Standard 2.0 / NET. Core

Last official version of "Microsoft.SolverFoundation" ported to .NET Standard 2.0 / NET. Core.

Overview

• Latest legacy version was taken from Nuget package "Microsoft.Solver.Foundation" and decompiled via ILSpy
• The code were just changed to be compilable as .NET Standard 2.0 class library.
• There is no unit test coverage as these tests were not included in the original library.
• There is just a functionality test with my custom scenario to verify that the original .NET Framework version produce the same output as the ported .NET 2.0 Standard library one.

What was changed during porting?

• The class CSharpWriter was commented out as it required "System.CodeDOM" from .NET Framework and was only used for "ExportModelToCSharp()" which was never called. So this method now throws a NotSupportedException.
• Configuration classes "ConfigurationElement", "ConfigurationSection" and "ConfigurationPropertyAttribute" were replaced by stubs. It belongs to the configuration and it seems it doesn't have an effect in the main logic.
• That't it. The rest of the code was just compiled and worked for my use case.

What to check if you use this port

• Run your model via .NET Framework and this port to verify correctness.
• You can use the projects Microsoft.SolverFoundation.ReferenceTests and Microsoft.SolverFoundation.Tests to verify your solver model.

Legal info

• The last known official version from "Microsoft.SolverFoundation" is "3.1.0" from "19.01.2017" licensed unter the MS-PL.
• Here is the ChatGPT answer of my question "Is decompilation and recompilation of MS-PL licensed binaries allowed?". So I assume there is no copyright violation:

Yes, the Microsoft Public License (Ms-PL) allows decompilation, modification, and recompilation of binaries, but with certain conditions.

Key Points of Ms-PL Regarding Decompilation & Recompilation

✅ You Can:

• Decompile the software to inspect, modify, or enhance it.
• Modify the source code and create derivative works.
• Recompile and distribute modified versions.

🚫 But You Must Follow These Rules:

1. No Warranty or Liability
   • The license disclaims all warranties and does not provide liability protection.
2. Preserve the License for Distribution
   • If you redistribute the modified software in source or binary form, it must still be licensed under Ms-PL.
   • You cannot change the license to a more restrictive one (e.g., GPL) but can combine Ms-PL code with other permissively licensed code.
3. No Trademark or Branding Rights
   • You cannot use Microsoft's trademarks, logos, or branding without permission when redistributing modified versions.

Practical Example

• If you decompile a Microsoft Solver Foundation Express binary, modify it, and recompile it, you must distribute it under Ms-PL and cannot claim it is an official Microsoft product.

Conclusion

Yes, decompilation and recompilation are allowed, provided you adhere to Ms-PL terms—especially regarding licensing and disclaimers. 🚀
