Building a ai saas with C#? Let us review it.
Expert code review for ai saas apps built with C#. We fix C#-specific security gaps, optimize performance, and handle deployment. From $19.
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.
AI SaaS challenges to solve
Key ai saas concerns that AI-generated code often misses.
Cost management and unit economics
Every user action costs you real money in API calls. If a user generates 100 requests a day and each costs $0.05, that's $5/day per user — $150/month. Without token tracking, usage tiers, and cost optimization, your AI SaaS can lose money on every customer.
Upstream API reliability
OpenAI and Anthropic APIs have outages, rate limits, and variable latency. Your SaaS needs fallback providers, retry logic with exponential backoff, request queuing, and graceful degradation. AI tools build direct API calls with no resilience — one upstream outage takes your entire product down.
Prompt management and versioning
Your prompts are your product's core IP. AI tools hardcode prompts in the source code. You need a prompt management system with versioning, A/B testing capability, and the ability to update prompts without deploying code. A bad prompt update shouldn't require a rollback of your entire application.
Output quality and consistency
AI responses vary in quality, format, and accuracy. Your paying customers expect consistent output. You need output validation, structured output parsing, retry logic for poor responses, and quality monitoring. One hallucinated response in a customer-facing context can destroy trust.
What we check
Key areas we review for C# ai saas projects.
API cost tracking — per-user and per-feature token usage monitoring
Upstream resilience — fallback providers, retry logic, circuit breakers
Prompt management — versioned prompts, separated from application code
Output validation — structured parsing, quality checks, error handling
