Deploy your C# app to Vercel
Step-by-step deployment help for C# apps on Vercel. We fix C#-specific deployment issues, configure Vercel, and get your app live. From $19.
C# issues we fix before deploying
Common C# problems that affect Vercel 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.
Vercel deployment issues we check for
Common Vercel problems that break C# apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.

Frequently asked questions
How do I deploy a C# app to Vercel?
We handle C# deployments to Vercel end to end. Start with our code audit ($19) to identify deployment blockers specific to your C# project, then we configure Vercel, fix issues, and get your app live in production.
What C# issues affect Vercel deployments?
C# projects commonly have async void methods and missing idisposable implementation. On Vercel, these combine with serverless function size exceeds 50mb limit and edge runtime incompatible with node.js apis to cause deployment failures.
Can SpringCode deploy my C# project to Vercel?
Yes. We specialize in deploying C# applications to Vercel. We audit your codebase for C#-specific issues, configure Vercel correctly, and handle the full deployment so your app runs reliably in production.
What does C# deployment to Vercel cost?
Our code audit ($19) identifies all Vercel deployment blockers in your C# project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
