Enhanced F# Language Features for Visual Studio Code
Part of the Ionide plugin suite. Read detailed documentation at Ionide docs page.
You can support Ionide development on Open Collective.
F# (Windows) - Easiest way to install latest versions of F# on Windows is using VS Build Tools 2017. If you use VS 2017, make sure that you've installed workload adding F# support.
F# (Linux/MacOS) - F# on non-Windows platform is distributed as part of the
mono. Installation guide and recent version of
mono can be found on the project webpage and on the F# Software Foundation "Use on Linux" page
.NET Core SDK - .NET Core is modern, cross-platform implementation of .NET Framework. Ionide is requiring it for set of features such as project modifications or debugging. The core part of SDK is
dotnet CLI tool that provides easy way to create, build and run F# projects. What's important - the
dotnet tool can be used also to create applications targeting also Full Framework (like
net461). For detailed instructions on installing .NET Core, visit official step-by-step installation guide.
VS Code C# plugin (optional) - Ionide's debugging capabilities relies on the debugger provided by Omnisharp team. To get it install C# extension from VS Code marketplace
MSBuild 2015 (Windows only, optional) - For old, verbose
.fsproj files on Windows MSBuild 2015 (14.0) needs to be additionally installed. You can download it here. However, we highly recommend using new, SDK-based project files.

How to contribute
Imposter syndrome disclaimer: I want your help. No really, I do.
There might be a little voice inside that tells you you're not ready; that you need to do one more tutorial, or learn another framework, or write a few more blog posts before you can help me with this project.
I assure you, that's not the case.
This project has some clear Contribution Guidelines and expectations that you can read here.
The contribution guidelines outline the process that you'll need to follow to get a patch merged. By making expectations and process explicit, I hope it will make it easier for you to contribute.
And you don't just have to write code. You can help out by writing documentation, tests, or even by giving feedback about this work. (And yes, that includes giving feedback about the contribution guidelines.)
Thank you for contributing!
