🔥 .NET 10 and C# 14 Are Finally Here And honestly… this is one of the most powerful .NET releases in recent years 👇 🟦 .NET 10 is an LTS Release It will receive 3 years of full support — until November 14, 2028. For companies running large production applications, this is a huge win. Stable. Secure. Future-ready. ⚡ The Biggest New Feature → File-Based C# Apps This update dramatically simplifies how you write and run C#. Earlier, even the smallest C# app required: a solution file (.sln) a project file (.csproj) and a .cs source file Now with .NET 10, you can create a single .cs file and run it directly: dotnet run main.cs This puts C# on the same level as Python, JavaScript, and TypeScript for scripting and utilities. Super clean. Super fast. 🚀 Top Improvements in .NET 10 ✔ Major performance boosts (JIT, runtime, hardware acceleration) ✔ Better security — improved cryptography, TLS updates ✔ Smaller container images for cloud-native apps ✔ ASP.NET Core 10 enhancements (minimal APIs, OpenAPI, Passkeys, SSE) ✔ EF Core 10 improvements (performance, JSON mapping) ✔ C# 14 refinements — cleaner syntax, better readability ✔ Improved build speed & reliability ✔ Better AI & Agent-based app support
