Deploy your C# app to GitHub Pages
Step-by-step deployment help for C# apps on GitHub Pages. We fix C#-specific deployment issues, configure GitHub Pages, and get your app live. From $19.
C# issues we fix before deploying
Common C# problems that affect GitHub Pages 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.
GitHub Pages deployment issues we check for
Common GitHub Pages problems that break C# apps in production.
Client-side routing returns 404 on refresh
React Router and other SPA routers break on page refresh because GitHub Pages doesn't support URL rewrites. Only the root index.html is served for the base path.
API routes have no server to run on
AI-generated Next.js or Express backends can't run on GitHub Pages. There's no server-side execution — only static HTML, CSS, and JavaScript are served.
Base path not configured for project sites
Project sites deploy to username.github.io/repo-name, but AI tools build with root (/) as the base path, breaking all asset and route references.
Custom domain DNS propagation issues
CNAME file missing from the build output or DNS records misconfigured, causing the custom domain to point nowhere or show GitHub's 404 page.

Frequently asked questions
How do I deploy a C# app to GitHub Pages?
We handle C# deployments to GitHub Pages end to end. Start with our code audit ($19) to identify deployment blockers specific to your C# project, then we configure GitHub Pages, fix issues, and get your app live in production.
What C# issues affect GitHub Pages deployments?
C# projects commonly have async void methods and missing idisposable implementation. On GitHub Pages, these combine with client-side routing returns 404 on refresh and api routes have no server to run on to cause deployment failures.
Can SpringCode deploy my C# project to GitHub Pages?
Yes. We specialize in deploying C# applications to GitHub Pages. We audit your codebase for C#-specific issues, configure GitHub Pages correctly, and handle the full deployment so your app runs reliably in production.
What does C# deployment to GitHub Pages cost?
Our code audit ($19) identifies all GitHub Pages deployment blockers in your C# project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
