AI Analysis

●●SolidBig BrainNiche Gem

Go/Swift syntax on .NET with real tooling, but F# already owns this niche.

Strengths
  • •Real tooling stack: LSP, VS Code extension, debugger with Portable PDB support
  • •Width-bearing primitives like int32 and float64 make value sizes explicit
  • •Full CLR interop means existing .NET libraries work without modification
Weaknesses
  • •F# already fills the alternative .NET language niche with stronger ecosystem
  • •C# 12+ added many modern features this language positions as differentiators
Target Audience

.NET developers wanting alternative syntax

Post Description

I started working on this back in 2019, mostly as a design idea. Over the last month I made a big push to make it 100% usable and replace C# in all my personal projects. I now feel it's solid enough to gather feedback from other developers. If you take it for a spin, I hope you enjoy it and send your thoughts!
