Simple physics game in F# and WPF

This is an example on how to use WPF and F# to do a simple physics game 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.

You control the ship by firing rockets attached to the ship. Use the arrow keys to fire the rockets.

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.

Tracing with Application Insights

Application logging is ubiquitous and invaluable for troubleshooting. Structured logging enables you to log formatted messages and the data fields separately so that you can see the messages but also filter on the data fields. Tracing takes this a step further, where you can correlate many log entries together as you follow a trace of execution through an application. Traces also include additional information about the execution process, such as the sequence of calls to dependencies and how long any given call may take.

Application Insights lets you see all of this data correlated together in an application. You can search for an error log and then see in the execution flow that the log entry was added right after a failed call to another service. Or you can see that a certain web request is slower than others because it spends a lot of time on many redundant data access calls.

What about OpenTelemetry?
