Ask it something hard.
Review this EF Core repository and fix the N+1 queries and the async void methods, then write xUnit tests for it.
CLAUDE · WITH THIS SKILL
You get: a numbered review of the pasted repository ordered by impact (lazy-loaded navigation in a loop causing N+1, async void swallowing exceptions, DbContext resolved as Singleton) -> the repository rewritten with Include and Select projections, AsNoTracking on read paths, Task-returning methods with CancellationToken -> the corrected DI registration with a Scoped lifetime -> xUnit tests using the EF Core SQLite in-memory provider, FluentAssertions and a Theory with InlineData -> a note that .NET 8 with nullable enabled is assumed and the single next command: dotnet build then dotnet test.

- LINQ and EF Core queries that translate to SQL, with projections
- xUnit tests, csproj, analyzers and dotnet CI steps ready to paste
Backend, ASP.NET Core, Blazor, MAUI and Unity developers who write C# every day and want a reviewer on every change.
// what's inside
What you're actually buying
This Claude/ChatGPT skill gives you a C# AI pair programmer for daily .NET work: it writes services and models with records, required members and nullable annotations, fixes async problems such as .Result deadlocks and missing CancellationTokens, writes LINQ and EF Core queries that actually translate to SQL, produces xUnit tests with FluentAssertions and NSubstitute, and sets up .csproj, Directory.Build.props and .editorconfig analyzers.
It knows pattern matching, records, collection expressions, primary constructors, Span and Memory, Task and ValueTask, Channel and BackgroundService, dependency injection lifetimes, ASP.NET Core minimal APIs, EF Core migrations, System.Text.Json and the dotnet CLI, plus the classic C# gotchas around structs, closures, DateTime and decimal. It does not build or run your solution; it writes and reviews, and you confirm with dotnet build and dotnet test.
Works the same way in Claude, ChatGPT and Gemini. One purchase, download the file, install in under 2 minutes, then paste your C# or the CS error you are stuck on. Pairs with Vesna, .NET Developer, the persona skill; this one is the helper inside C#.
# AI Skill for C# KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then just ask questions the way you normally would. ## Who you are You are a senior C# developer acting as the user's pair programmer. You know modern C# and .NET: the language, the BCL, async, LINQ, the dotnet CLI, and how C# is used in ASP.NET Core, EF Core, console tools, Blazor, MAUI and Unity. You optimise for code that is correct under nullable reference types, readable, testable, and idiomatic for the .NET version in use. You are a helper inside the language, not a job-role persona: you write, review, explain and debug C# alongside the user. Tone: direct, practical, code first, one-line reason when a choice matters. ## What you know about C# - Language features: LINQ, `async`/`await`, pattern match

Questions about this product
What does the AI Skill for C# do?+
It makes Claude or ChatGPT act as a C# AI pair programmer inside your daily .NET work. It writes idiomatic C# classes, services and records, fixes compiler errors and exceptions, untangles async and concurrency problems, writes LINQ and EF Core queries, sets up projects and CI with the dotnet CLI, writes xUnit tests, and reviews your C# code with fixes ordered by impact.
Does it build or run my C# project for me?+
No. The skill does not execute dotnet build, dotnet test or dotnet ef commands. It writes and reviews the C# code, tells you exactly which command to run next, and marks any assumption about your .NET version, C# language version or nullable settings so you can confirm locally.
Which .NET and C# versions does it cover?+
It covers modern C# from LINQ and async through records, pattern matching, required members, primary constructors and collection expressions, and it asks for your TargetFramework and LangVersion before relying on a newer feature. It will not invent C# APIs, NuGet packages or MSBuild properties.
Does it help with ASP.NET Core, EF Core and Unity C#?+
Yes for ASP.NET Core and EF Core: minimal APIs, controllers, DI lifetimes, middleware, DbContext, migrations and query translation are core scenarios. For Unity it covers the C# language side and asks about the Unity runtime constraints, since some .NET features behave differently there.
Which AI tools does this skill work with?+
Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it remembers your C# solution layout, .NET version and coding conventions between chats.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
