Expert C# Code Review for AI-Built Apps
C# powers enterprise applications, Unity games, and .NET web APIs. AI tools generate C# code that often mishandles async/await, ignores IDisposable patterns, and lacks proper authorization in ASP.NET endpoints.
Common C# issues we find
Real problems from C# codebases we've reviewed.
Async void methods
Using async void instead of async Task in non-event-handler methods, causing unhandled exceptions that crash the process silently.
Missing IDisposable implementation
Database connections, HTTP clients, and file streams not disposed properly, causing resource exhaustion under load.
Insecure deserialization
Using BinaryFormatter or Newtonsoft with TypeNameHandling.All to deserialize untrusted data, enabling remote code execution.
Missing authorization attributes
ASP.NET controller actions without [Authorize] or policy-based checks, exposing endpoints to unauthenticated users.
Deadlocks from .Result and .Wait()
Blocking on async calls with .Result or .Wait() in synchronization contexts, causing deadlocks that freeze the application.
Connection string in source code
Database connection strings hardcoded in appsettings.json or source files instead of environment variables or Azure Key Vault.
C# production checklist
Key checks before deploying your C# app.
No async void methods (except event handlers)
All IDisposable objects properly disposed (using statements)
No .Result or .Wait() on async calls
Authorization attributes on all controller actions
Connection strings and secrets in environment variables
No BinaryFormatter or unsafe deserialization
Health checks configured for production monitoring
Logging with ILogger (not Console.WriteLine)
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Is AI-generated C# code production-ready?
AI tools generate working C# but consistently miss enterprise patterns like proper async/await, IDisposable, authorization, and secrets management. These gaps cause crashes and security vulnerabilities in production.
Can you review my ASP.NET application?
Yes. We review endpoint authorization, middleware configuration, dependency injection, Entity Framework usage, and deployment configuration across the full .NET stack.
How do you handle .NET deployment?
We configure production builds, set up Azure or AWS hosting, implement health checks, configure logging and monitoring, and establish CI/CD pipelines.
Can you fix async/await issues in my C# code?
Yes. We eliminate async void, replace .Result/.Wait() with proper await, fix deadlocks, and implement cancellation token patterns for responsive applications.
