Most .NET projects eventually accumulate the same small pieces of code: string and collection helpers, validation rules, security-related utilities, and test data generation.
None of these problems are particularly large individually. The cost comes from solving them repeatedly across projects.
That is why I built SaddamHossain.Toolkit — a collection of focused NuGet packages for common .NET development tasks.
The first release includes v1.0 of four packages.
SaddamHossain.Toolkit.Extensions
Practical helpers for everyday .NET development, covering common operations around strings, dates, numbers, GUIDs, and collections.
The goal is simple: provide reusable APIs for the small pieces of code developers repeatedly write across projects.
dotnet add package SaddamHossain.Toolkit.Extensions
SaddamHossain.Toolkit.Validation
Focused validators for common application input.
It provides reusable validation for supported scenarios such as email, phone, URL, identity values, password strength, and structured data—helping keep validation logic clear and consistent.
dotnet add package SaddamHossain.Toolkit.Validation
SaddamHossain.Toolkit.Security
Security-sensitive functionality deserves the right primitives rather than another ad-hoc implementation.
This package provides focused helpers for passwords, hashing, secure tokens, password strength, and cryptographically secure randomness.
SaddamHossain.Toolkit.FakeData
Good tests need more than a handful of hard-coded values.
FakeData generates realistic, strongly typed data for testing, development, demos, and database seeding.
Deterministic generation is especially useful when a test fails and you need to reproduce the same data to investigate the problem.
dotnet add package SaddamHossain.Toolkit.FakeData
Why four focused packages?
I intentionally didn't make one large package containing everything.
Each package solves a different problem and can evolve independently.
Need everyday helpers? Extensions.
Need reusable input validation? Validation.
Need security-related primitives? Security.
Need realistic, reproducible test data? FakeData.
Install only what your project needs.
What's next?
These are v1.0 releases.
I'll continue improving the packages gradually based on real-world usage, developer feedback, and community suggestions.
The goal isn't to build the biggest .NET toolkit.
It's to build focused libraries that solve real, recurring problems and are easy to adopt.
If you're working with .NET:
What small problem do you repeatedly solve that deserves its own NuGet package?
I'd genuinely love to hear your ideas. Your suggestion could become a future package.
