Deploy a .NET App for Free on Railway (No Credit Card)

Deploying a .NET application on Railway.app(click here) involves a series of steps to prepare your application for deployment and configure Railway for successful hosting. Here’s a guide to help you:

---

Step 1: Prepare Your .NET Application

1. Ensure the Application is Ready for Deployment:

   • Verify that your application runs locally without errors.
   • Include a Dockerfile or use Railway's default buildpacks if you’re not using Docker.

2. Add Necessary Configuration Files:

   • Add a appsettings.json for environment-specific configurations.
   • Use environment variables for sensitive information like database connections or API keys.

3. Build and Test Locally:

   • Use the following command to ensure your app builds:

     dotnet publish -c Release

---

Step 2: Push Your Code to a Git Repository

Railway integrates with Git repositories (e.g., GitHub, GitLab). Ensure your code is pushed to a repository.

1. Sign in to Railway.app:

   • Go to Railway.app(click here) and log in.

2. Create a New Project:

   • Click New Project and choose your repository or deploy from an empty template.

3. Choose a Deployment Method:

   • Use GitHub Integration:
     • Connect your Railway account to GitHub.
     • Select the repository containing your .NET application.
   • Manual Deployment:
     • Upload your code directly to Railway.

Step 4: Configure Build Settings

1. If Using Buildpacks:

   • Set the .NET version in Railway.toml or rely on autodetection.

2. If Using Docker:

   • Ensure you have a Dockerfile in the root of your project:

     FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base
     WORKDIR /app
     EXPOSE 80
     
     FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
     WORKDIR /src
     COPY . .
     RUN dotnet restore
     RUN dotnet publish -c Release -o /app
     
     FROM base AS final
     WORKDIR /app
     COPY --from=build /app .
     ENTRYPOINT ["dotnet", "YourAppName.dll"]

---

Step 5: Add Environment Variables

1. Go to the Settings tab in your Railway project.
2. Add required environment variables (e.g., ASPNETCORE_ENVIRONMENT, ConnectionStrings).

---

Step 6: Deploy the Application

1. Railway will automatically detect and deploy your application based on the configuration.
2. Monitor the logs in the Railway dashboard to ensure successful deployment.

---

Step 7: Test Your Application

1. Once deployed, Railway provides a URL for your application.
2. Open the URL to verify the application works as expected.

---

Optional: Connect to a Database

1. If your application uses a database, add a Railway-provided database plugin (e.g., PostgreSQL, MySQL).
2. Update your application's connection string with the provided credentials.

---

This process ensures your .NET application is properly deployed on Railway.app.
