Simple physics in F# and WPF

This is an example on how to use WPF and F# to do some simple physics using Verlet Integration.

The program creates a system of particles and constraints. Particles have inertia and is affected by gravity but their motion is also contrained by the constraints.

I tried to annotate the source code to help guide a developer familiar with languages like C#. If you have suggestions for how to improve it please leave a comment below.

On the topic of tail calls in .NET

Let's say you have implemented a small data pipeline library to replace LINQ.

module TrivialStream =
  type Receiver<'T> = 'T            -> unit
  type Stream<'T>   = Receiver<'T>  -> unit

Deploying an F# ASP.NET Core app to Azure

Last week I spent a lot of time trying to deploy an F# ASP.NET Core app (a Giraffe app, specifically) to Azure because the information to complete all the steps was scattered in several places. So I'm writing this hopefully it will save the pain to others :)

Preparation

The following steps are mostly taken from this guide and it's only necessary to do them once:

1. Create an account in Azure (or use an existing one)
2. Create a resource group (or use an existing one)
