# How to Deploy ASP.NET Core App in 2026 (No DevOps Needed) > Deploy an ASP.NET Core app in 2026 without SSH, Docker, or server setup. Step-by-step guide using Kuberns with AI automation, env vars, and auto-scaling. - **Author**: riddhi-dudhatra - **Published**: 2026-04-28 - **Modified**: 2026-04-28 - **Category**: Deployment Guides - **URL**: https://kuberns.com/blogs/deploy-dotnet-aspnet-core-app/ --- Deploying an ASP.NET Core app to production looks simple until you actually try it. Your app works fine on `localhost`. But getting it live means choosing a server, installing the correct .NET runtime, binding Kestrel to the right port, putting Nginx in front of it, running Certbot for SSL, writing a systemd unit to keep the process alive, and then wiring up CI/CD so you are not manually SSHing in every time you push a change. On Azure App Service, the steps are different but the overhead is similar: publish profiles, app settings navigation, scaling tied to fixed plan upgrades, and a portal that has more configuration options than most apps ever need. None of that is your app. It is all infrastructure work that sits between your code and a live URL. [Kuberns](https://kuberns.com/) removes that entire layer. It is an agentic AI deployment platform that reads your `.csproj`, runs `dotnet publish`, starts your app on AWS, handles SSL, and manages auto-scaling automatically. You push to GitHub. It takes care of the rest. **What this guide covers:** - What to confirm before deploying (two things only) - Step-by-step deployment on Kuberns with screenshots - Connecting a database with Entity Framework Core - A comparison of ASP.NET Core deployment platforms in 2026 - The most common deployment errors and how to fix them ## Before You Deploy: Two Things to Confirm You do not need to restructure your project or add any configuration files. There are just two things to check. ### 1. Your app reads PORT from the environment Kuberns injects the port your app should listen on via a `PORT` environment variable. Update `Program.cs` to read it: ```csharp var port = Environment.GetEnvironmentVariable("PORT") ?? "8080"; builder.WebHost.UseUrls($"http://0.0.0.0:{port}"); ``` Binding to `0.0.0.0` (not `localhost`) is required so the platform can route external traffic to your app. ### 2. Your project is on GitHub Kuberns deploys directly from your repository. No Dockerfile. No Procfile. No publish profile. ## How to Deploy an ASP.NET Core App on Kuberns (Step by Step) [Kuberns](https://kuberns.com/) is an agentic AI deployment platform that auto-detects your .NET project, runs `dotnet publish`, provisions compute on AWS, issues SSL, and sets up CI/CD automatically. No configuration files required. ### Step 1: Create Your Kuberns Account ![sign-up-to-kuberns](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/kuberns-homepage.png) Go to [kuberns.com](https://kuberns.com/) and click **Deploy for Free**. Create your account and verify your phone number. Kuberns has a free tier to start. After that, $7 gets you $14 in compute credits - 2x value to apply toward your deployment. [See what each tier includes](https://kuberns.com/pricing/). ### Step 2: Connect Your GitHub Repository ![Connect GitHub to Kuberns](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/kuberns-registration.png) On the **Creating a Service** page, connect your GitHub account and select your ASP.NET Core repository and branch. - Click **Connect & Configure** and authorise Kuberns access to your repositories - Select your repository and the branch you are deploying (typically `main`) - Kuberns AI scans your project and automatically detects the target framework from your `.csproj`, the build command (`dotnet publish -c Release`), and the project type (Web API, MVC, Blazor Server, minimal API) You confirm, not configure. ### Step 3: Add Environment Variables ![Environment variables on Kuberns](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/environment-variable-kuberns.png) Before clicking Deploy, navigate to the Environment section: - Click **Add Env Vars** and input key-value pairs manually, or - Click **Upload .env file** to import all variables at once For a typical ASP.NET Core app, add: | Variable | Value | |---|---| | `ConnectionStrings__DefaultConnection` | Your database connection string | | `ASPNETCORE_ENVIRONMENT` | `Production` | | `JWT_SECRET` or other auth secrets | Your values | ASP.NET Core maps double-underscore (`__`) separated variable names directly to nested config keys. So `ConnectionStrings__DefaultConnection` is read automatically via `Configuration.GetConnectionString("DefaultConnection")` in your code. Kuberns encrypts all values at rest. They never appear in build logs. ### Step 4: Click Deploy - The AI Takes Over ![Kuberns AI deploying ASP.NET Core app](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/agent-deployment-process.png) Click **Deploy**. From here you watch rather than configure. Kuberns agentic AI: - Clones your repository from GitHub - Detects .NET from your `.csproj` and reads the target framework version - Runs `dotnet restore` then `dotnet publish -c Release` - Starts the published binary with `ASPNETCORE_ENVIRONMENT=Production` and the injected PORT - Provisions AWS compute in your chosen region - Issues an SSL certificate and assigns a live HTTPS URL - Enables monitoring, logging, and AI-driven auto-scaling - Sets up CI/CD so every future Git push triggers an automatic redeploy ### Step 5: Access Your Live ASP.NET Core App ![Kuberns deployment dashboard](https://kuberns-blogs-media.s3.ap-south-1.amazonaws.com/deployed-dashboard.png) Your ASP.NET Core app is live in under five minutes. From the Kuberns dashboard you can: - Open your deployed HTTPS URL - View live usage stats and resource consumption - Check real-time logs and build history - Manage environment variables without redeploying - Monitor AI-driven auto-scaling metrics [Deploy your ASP.NET Core app on Kuberns →](https://dashboard.kuberns.com) ## Deploying ASP.NET Core with Entity Framework Core and PostgreSQL Most ASP.NET Core apps use Entity Framework Core with a relational database. Here is how to connect it on Kuberns. ### Register your DbContext In `Program.cs`, use the connection string from `IConfiguration`: ```csharp builder.Services.AddDbContext(options => options.UseNpgsql(builder.Configuration.GetConnectionString("DefaultConnection"))); ``` ### Add the connection string to Kuberns In the Kuberns environment tab, add `ConnectionStrings__DefaultConnection` with your full Postgres connection string: ``` Host=your-db-host;Database=your-db;Username=your-user;Password=your-password;SSL Mode=Require ``` Your app reads it at runtime via `IConfiguration`. No code changes needed between local and production beyond using environment variables instead of hardcoded values. ### Recommended database providers - **Neon** for serverless PostgreSQL with connection pooling, generous free tier - **Supabase** for managed PostgreSQL with a dashboard - **AWS RDS** for PostgreSQL on the same AWS infrastructure as Kuberns, lowest latency > On a VPS, you would also install PostgreSQL, configure `pg_hba.conf`, create a database user, set permissions, and wire everything up manually before your first migration. On Kuberns, you paste a connection string and you are done. ## What Kuberns Handles vs What You Do Manually | ASP.NET Core requirement | VPS / Azure App Service | Kuberns | |---|---|---| | .NET runtime version | Select and configure manually | Auto-detected from .csproj | | dotnet publish | CI pipeline or publish profile | Runs automatically on every deploy | | Kestrel port binding | Configure in Program.cs manually | Injected via PORT env variable | | Reverse proxy (Nginx/IIS) | Install and configure | Not required | | SSL certificate | Certbot or Azure certificate | Automatic | | Environment variables | Server config or Azure portal | Encrypted in dashboard | | Auto-scaling | Azure plan upgrade or manual rules | AI-driven | | CI/CD pipeline | GitHub Actions YAML or Azure Pipelines | Built-in on every Git push | | Custom domain with HTTPS | DNS + certificate binding | One-click in dashboard | | Process restart on crash | systemd or Azure health checks | Automatic | ## ASP.NET Core Deployment Platform Comparison (2026) | Platform | Auto-detects .NET | Docker required | Free tier | Auto-scaling | Starting price | Best for | |---|---|---|---|---|---|---| | **Kuberns** | Yes, from .csproj | No | Yes, free credits | AI-driven | $7/mo | Full-stack .NET, zero-ops teams | | Azure App Service | Yes | No | Yes (F1, very limited) | Manual plan upgrade | $13/mo | Teams already on Azure | | Render | Yes | Recommended | Yes (sleeps on idle) | Rules-based | $7/mo | Heroku migrations | | Railway | Partial | Optional | Trial credits only | Limited | $5/mo + usage | Prototypes | | Fly.io | No | Yes | None (removed 2024) | Manual | $5/mo + usage | Devs who prefer config | | VPS with systemd | Manual | Optional | No | Manual | ~$5/mo | DevOps-heavy teams | For teams evaluating other options, our guide on [Heroku alternatives for app deployment](https://kuberns.com/blogs/the-ultimate-guide-to-heroku-alternatives-in-2025/) covers the full landscape. ## Common Deployment Issues and Fixes **App returns 502 immediately after deploy** Your app is binding to `localhost` or a hardcoded port. Update `Program.cs` to use `Environment.GetEnvironmentVariable("PORT")` bound to `0.0.0.0` as shown in the prerequisites section. **Build fails with "project not found"** Kuberns looks for a `.csproj` at the repository root. If your project is in a subdirectory, set the root directory in the Kuberns service settings to point at the correct folder. **Database connection fails at runtime** Confirm your connection string uses the double-underscore format (`ConnectionStrings__DefaultConnection`) and includes `SSL Mode=Require` for managed PostgreSQL providers. **EF Core migrations not running on deploy** Kuberns does not run `dotnet ef database update` automatically. Add `dbContext.Database.Migrate()` inside `Program.cs` before `app.Run()` to apply migrations on startup. **App works in Development but fails in Production** A required environment variable is missing. Check the Kuberns logs tab, find which `IConfiguration` key returned null, and add it in the Environment tab.
