Introducing F# Analyzers

One of the most exciting features of Roslyn (modern C# compiler) is ability to plug into it custom extensions called Roslyn Analyzers. They are live, real-time, project based plugins that enables to diagnose source code and surface custom errors, warnings and code fixes into Visual Studio. What’s really important is fact that there are project based, and distributed through NuGet which means they are easy to install, and ensure that all developers working on the project have exactly same analyzers installed. This is really useful if you want to ensure common best practices, style etc while working on the project.

Today I’d like to introduce preview of the project called F# Analyzers which adds similar capabilities to Ionide (F# support in VS Code). Project is still in the early days, so design and technical details can change in time, but I’m really excited to share it with users even in its current state.

But it’s also important to understand that an MVP software development is not synonymous with unfinished or a primitive product that was created in a hurry.

Open Source Software has won. After years of convincing people to use open source software, fighting with false dichotomy between OSS and industrial, commercial software, and defending against negative biases, position of OSS is no longer disputed - it’s been used by vast majority of companies around the world, it has become default choice when choosing technologies, it powers the internet, our PCs, mobile phones and most devices we use every day, it’s been accepted by huge, conservative companies that were against whole concept few years ago.

But have we really been ready for that? For most of its history OSS community was busy fighting for survival. And we created strategy, methodologies, and public relations attitudes that were helping us fight for this survival. But the times have changed and now we face totally different set of problems that we need to solve.

Introduction

Azure Functions is a service that provides serverless execution model while running code in the cloud. Serverless model is getting more and more popular nowadays, being great solution for building distributed, scalable, event-driven applications. However, those are not the only use cases - compute-on-demand story, automatic, low friction scalability and great pricing model means that Azure Functions can be used to host normal (REST-ish) APIs.

On the other hand, Saturn is new F# web framework that provides flexible, high level model of creating web applications using principles of functional programming and MVC architectural pattern. Main design goals of Saturn includes high level abstractions that lets developers focus on creating business code , and general developer experience.
