vvvv — visual programming for .NET
summary
VL is a visual .NET language and vvvv gamma is its live IDE that compiles visual patches to in‑memory C# via Roslyn and supports hot state reload, allowing edits while the app keeps running. It mixes dataflow with OOP, full generics and type inference, events → observables, loops with per-iteration state and incremental assembly emission. Demo runs slides as a live patch, loads a Microsoft Cognitive Services NuGet for speech, and hot-swap works most of the time (failures are rare, ~1%); deployment and .NET Core porting are in progress.
