Alternative to .net

SubscriptionEnterpriseOn-premises, CloudMIT LicenseOpen CorePublic APISDK

Best for

Porting legacy .NET Framework applications to non-Windows platforms.

Cost

Open source, free to use with optional professional support from Xamarin/Red Hat.

Summary

An open-source implementation of Microsoft's .NET Framework for cross-platform compatibility.

Why Switch

Need to run existing .NET Framework applications on Linux or macOS without full rewrite.

SOC2GDPR

Migration Playbook

  1. Export existing .NET Framework binaries and source code ensuring compatibility with Mono-supported APIs.
  2. Map Windows-specific APIs to Mono equivalents and adjust project files to Mono-compatible formats (e.g., .csproj).
  3. Import projects into MonoDevelop or compile using Mono CLI tools, then deploy on Linux or macOS environments.

Pros

  • 🟢Allows running .NET applications on Linux and macOS
  • 🟢Supports many .NET APIs and libraries
  • 🟢Facilitates reuse of existing .NET code

Cons

  • 🔴Not fully compatible with latest .NET Core/.NET 5+ features
