UniGetUI
UniGetUI: The Graphical Interface for your package managers. Could be terribly described as a package manager manager to manage your package managers
Project mention: Microsoft wants Windows Update to handle all apps | news.ycombinator.com | 2025-05-28I recently came across Uniget (https://github.com/marticliment/UniGetUI) and have been pretty pleased with how it works.

💡 For the more curious, Commitji is written in F# to follow the functional programming principles, including the Elmish MVU pattern. It relies on Spectre.Console, a great library in particular for rendering in a command terminal.

-
CSharpRepl
A command line C# REPL with syntax highlighting – explore the language, libraries and nuget packages interactively.
It should be able to! F# has "gradual typing" and full type inference which means you often do not need to specify the types at all, and it also happens to be whitespace-sensitive language much like Python is. Both of these aspects should make it feel quite familiar while also giving you full advantages of static typing.
One thing to note is I find `dotnet fsi {some script name}.fsx` taking more time to start than ideal - up to 800ms is just too much, normal .NET applications usually start in a fraction of this.
I recently posted a submission for "FSharpPacker" that lets you compile F# scripts to standalone applications (either runtime-dependent, self-contained or fully native binaries, much like Go), it also has some comments on getting the best mileage out of it: https://news.ycombinator.com/item?id=42304835
Probably the best feature that also comes with scripting (both C# and F#) is "inline" nuget references e.g. #r "nuget: FSharp.Control.TaskSeq" which will automatically pull the dependency from nuget without ever dealing with manually installing it or tinkering with build system in any other way.
Some additional links:
https://learn.microsoft.com/en-us/dotnet/fsharp/tools/fsharp...
https://github.com/dotnet-script/dotnet-script (C# is also a quite productive language for scripting and small programs because of top-level statements, record types, pattern matching and many other functional features though perhaps not as strongly represented as in F#)

Core functionality needed to create .NET Core projects, that is shared between Visual Studio and CLI (by dotnet)
I opened an issue since I couldn't find docs that indicate what they were working on to improve the start time, and they replied:
