Deploy your C# app to Railway
Step-by-step deployment help for C# apps on Railway. We fix C#-specific deployment issues, configure Railway, and get your app live. From $19.
C# issues we fix before deploying
Common C# problems that affect Railway deployments.
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.
Railway deployment issues we check for
Common Railway problems that break C# apps in production.
Nixpacks detects the wrong build system
Monorepo projects or apps with multiple package managers confuse Nixpacks auto-detection, resulting in incorrect build commands and failed deployments.
Volume data lost on redeploy
AI-generated apps store uploaded files or SQLite databases on the filesystem without configuring Railway volumes, losing all data on each new deployment.
Private networking misconfigured between services
Internal service communication uses public URLs instead of Railway's private network (*.railway.internal), adding latency and exposing internal APIs publicly.
Health check endpoint missing
Railway restarts services that fail health checks. AI-generated servers often lack a /health endpoint, causing unnecessary restart loops.
