I am delighted to announce the release of Spargine 10 (v2026.10.4.1) on April 1st, 2026. Spargine, my open-source project, now offers NuGet packages for .NET 10. These enhancements have been integrated across all my projects. I encourage you to explore these updates and share any feedback or suggestions for further improvements.

This version supports .NET 10, introduces new types, methods, benchmarks, and comprehensive unit tests, all aimed at improving Spargine’s performance and reliability! Notably, this release includes speed enhancements informed by benchmark tests outlined in the 5th edition of Rock Your Code: Code & App Performance for Microsoft .NET, available on Amazon.

Performance Enhancements: Significant Speed Improvements Across Methods

With every new release of Spargine, I continue to refine performance — and the .NET 10 version delivers substantial speed gains across many methods. Some improvements came because of careful tuning and benchmarking (sometimes with help from Copilot — with mixed results).

Here are the most notable speed increases:

• App.ProcessPath(): 2x faster.
• CollectionExtensions.AddRange(): 1.49x faster.
• EnumerableExtensions.Create(): 86x faster with decreased allocations by 6x.
• EnumerableExtensions.ToBlockingCollection(): 4.66x faster and decreased allocations by 3x.
• ListExtensions.ToObservableCollection(): 28x faster and decreased allocations by 14x.
• ListExtensions.ToReadOnlyObservableCollection(): 28x faster and decreased allocations by 10x.
• LoggingHelper.LogApplicationInformation(): 775x faster.
• PasswordGenerator.GeneratePassword(): 1.84x faster.
• StringExtensions.CalculateTotalLength(): 3.3x faster with no allocations.
• StringExtensions.HasValue() – String: 9.74x faster.
• StringExtensions.HasValue() – using length: 1.64x faster.
• StringExtensions.HasValue(): 2,535x faster.
• StringExtensions.HasWhitespace(): 2.74x faster.
• TypeHelper.GetAllGenericMethods(): 23.9x faster and decreased allocations by 15.8x.
• TypeHelper.GetAllPublicMethods():  8.08x faster and decreased allocations by 15.13x.
• TypeHelper.GetAllStaticMethods(): 16.28x faster and decreased allocations by 9.4x.
• TypeHelper.GetAttribute() – FieldInfo: 2.6x faster.

Summary

I’m confident these new and enhanced Spargine features will significantly improve your projects by boosting both performance and reliability. Detailed benchmark results are available on GitHub for those who want to dig deeper.

As always, open-source thrives on community involvement. If you find these updates helpful — or have ideas for future improvements — I encourage you to jump in. Whether through pull requests, issue reports, or feature suggestions, your contributions are invaluable.

Together, we can continue to make Spargine a robust and indispensable tool for the .NET community. Your feedback is always welcome, so please share your thoughts in the comments.

If my work has helped you write faster, cleaner, rock-solid .NET code, I’d love your support through GitHub Sponsors. Your sponsorship helps fuel new features, benchmarks, tools, and learning resources for the entire community.
