AI for .NET Developers

Best prompt templates across 6 everyday scenarios

Copy → Adapt → Validate → Ship faster

Vague prompts produce vague code. AI tools like Claude, GitHub Copilot, and ChatGPT are only as good as the context you give them. Developers who specify their .NET version, libraries, architecture, and expected output consistently get production-ready results — those who don't get generic boilerplate. These templates fix that.

"Fix this" → AI freezes.
Context + task + constraints → impressive output.

Stop wasting prompts. Better prompts = better code, faster delivery, fewer rewrites.

⚡

Code Generation

"Create a .NET 8 minimal API with CRUD, validation, and proper error handling."

"Write a generic repository pattern using EF Core with async methods."

"Generate a Blazor data table (MudBlazor) with sorting, pagination, and search."

→ Always specify: .NET version + libraries (EF Core, MediatR, MudBlazor…)

🐛

Debugging

"Here is my stack trace: [paste]. Identify root cause and provide a fix with explanation."

"My LINQ query returns incorrect results. Find the logical issue."

"Why does this async/await code deadlock? Rewrite it safely."

→ Include: actual error message + relevant code snippet

🏗️

Architecture

"Design a scalable microservices architecture using .NET + Azure Service Bus."

"Compare Clean Architecture vs Vertical Slice for a team of 5 developers."

"Suggest CQRS + MediatR structure with domain events."

→ Mention: team size, scale (startup/enterprise), cloud provider

🧪

Testing

"Write xUnit tests using Moq for this service (include edge cases)."

"Generate integration tests using TestContainers + WebApplicationFactory."

"My test is flaky. Identify timing issues and fix them."

→ Define: framework (xUnit/NUnit) + mocking lib (Moq/NSubstitute)

🚀

Performance

"Optimize this LINQ query for better performance (compiled queries or raw SQL)."

"Identify memory leaks and suggest IDisposable / using patterns."

→ Provide: benchmark data + query size / dataset context

🔍

Code Review

"Review this C# class for SOLID violations and suggest refactoring."

"Check for security issues (SQL injection, insecure deserialization, etc.)."

→ Ask for: SOLID, DRY, YAGNI + security + performance review

The perfect prompt formula

Context + Task + Constraints + Output format

"I'm using .NET 8 + EF Core + PostgreSQL. Write a paginated product query with filtering.
Return clean C# code with XML comments + a usage example."
