ASP.NET Core Guide

Best Hosting for ASP.NET Core (2026)

Compare the best hosting platforms for ASP.NET Core. We review Azure, Railway, and more with .NET deployment patterns.

ASP.NET Core runs cross-platform, opening many hosting options beyond Windows. We've evaluated platforms that handle .NET applications well.

Why This Matters

ASP.NET Core's cross-platform nature means you're not locked into Azure. Choose based on cost, features, and operational requirements rather than platform constraints.

Key Considerations

Azure Integration

Azure App Service has first-party .NET support. Managed identity, easy scaling, integrated monitoring.

Container Deployment

ASP.NET Core runs in containers on any platform. Use mcr.microsoft.com/dotnet/aspnet base images.

Linux vs Windows

Linux containers are smaller and cheaper. Windows only needed for specific dependencies. Most apps work on Linux.

Health Checks

Use ASP.NET Core health checks middleware. Configure platform to use /health endpoint.

AOT Compilation

.NET 8+ supports Native AOT for faster startup. Consider for serverless deployments.

Frequently Asked Questions

What's the best free hosting for ASP.NET Core? ▼

Railway offers $5/month credit. Render has free tier with spin-down. Azure App Service F1 tier is free but limited. Fly.io offers 3 free VMs.

Should I use Windows or Linux hosting? ▼

Use Linux for most apps—containers are smaller and hosting is cheaper. Only use Windows if you have Windows-specific dependencies.

How do I deploy from Visual Studio? ▼

Right-click project → Publish → Azure App Service. Or use 'dotnet publish' and deploy the output to any platform.

What about serverless for ASP.NET Core? ▼

AWS Lambda supports .NET 8 with Native AOT for fast cold starts. Azure Functions also supports .NET. Consider for event-driven workloads.
