Refactor Code for your C# project
Expert refactor code for C# applications. We find and fix C#-specific bugs and security issues that affect production apps. From $19.
C# refactor code issues we find
Common refactor code problems specific to C# applications.
Async void methods
Using async void instead of async Task in non-event-handler methods, causing unhandled exceptions that crash the process silently.
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.
What our C# refactor code covers
Component restructuring
Breaking down god components into focused, reusable pieces with clear responsibilities.
Code deduplication
Identifying and consolidating repeated logic into shared utilities and hooks.
Architecture improvement
Separating concerns — UI from business logic, data fetching from rendering, config from code.
Type safety
Adding or improving TypeScript types to catch bugs at compile time instead of runtime.
Error handling patterns
Implementing consistent error handling, logging, and user-facing error messages throughout the app.
Dependency cleanup
Removing unused packages, updating outdated dependencies, and consolidating redundant libraries.
