They're the utilities I built to solve real client delivery problems — cleaned up, documented, and open-sourced so you don't have to rebuild them. The same instinct that produces a clean, reusable library is the one I bring to client work: find the actual problem, then fix it properly.
The ones people use most
Benday.Common
20,000+ downloads
Foundational helpers and patterns that show up in nearly every .NET app I build — the base layer the rest of these libraries sit on.
Benday.EfCore.SqlServer
16,000+ downloads
Entity Framework Core patterns and helpers for SQL Server — repositories, testability, and the plumbing that usually gets copy-pasted between projects.
slnutil
15,000+ downloads
A dotnet command-line tool for wrangling Visual Studio solution files and everyday .NET project housekeeping — the kind of thing you script once and never think about again.
Benday.CommandsFramework
11,000+ downloads
A framework for building command-line tools in .NET — it's the engine underneath azdoutil and slnutil.
azdoutil
11,000+ downloads
A dotnet command-line tool for administering Azure DevOps — scripting project setup, process templates, and configuration so it's repeatable instead of click-by-click.
Benday.CosmosDb
5,900+ downloads
A repository and helper library for Azure Cosmos DB — and the working code behind the book.
That's the short list. There are 20+ packages in all — ASP.NET Core Identity stores backed by Cosmos DB, JSON and XML utilities, presentation-layer helpers, GitHub admin tooling, and more.

I wrote the book, too
Azure Cosmos DB for .NET Developers
The practical, code-first guide to building real applications on Cosmos DB — data modeling, querying, performance and cost, security, the change feed, and reporting with Fabric. The same material that powers Benday.CosmosDb.

Building and maintaining tools like these is the same muscle I bring to client work — diagnosing the real problem, then fixing it in a way that holds up. If your team is stuck and you want someone who can both see the structural issue and write the code to get past it, let's talk.
