Try-Catch-Throw in C#

We had an interesting discussion in a team meeting today and a good point was brought up about try/catch blocks and what happens when you throw an error in the catch section that perhaps a lot of developers new to C# might not be aware of.

C# Advent 2024 - Making a List, Checking It Twice

He’s making a list Checking it twice Writing some code To track who’s naughty and nice Santa Claus is wri-ting… C# tldr; With .NET 9, you can now add custom action buttons to the .NET Aspire dashboard screen You ever wonder how Santa is able to keep track of the kids who are naughty and nice? I mean, it was probably fairly easy when an old man could send out his army of short helpers to check up on the handful of kids who fell into his purview from time to time through the year, and to keep all that recorded on paper. But today? With the world’s population exploding? How on Earth could he possibly do that now? With each passing year it’s gotten harder and harder. Never fear, Santa, I got ya covered. Let me throw together a quick proof of concept (POC) and show you the future!

Using C# and Power Automate To Sync An Outlook Calendar

There are some good tools out there for syncing your Outlook calendar to other calendars, especially for O365 or Outlook.com calendars. And they’re well worth the money for the good ones. But sometimes, in certain circumstances (such as if you have an on-prem exchange server that you can’t access from the cloud), you just need a quick and dirty tool to copy calendar events from a local Outlook instance to another calendar. That’s something you can do pretty quickly with a little C# and some Power Automate.

Turning Any JSON API Into An App

The Internet is fantastic. There are a seemingly infinite array of APIs available for people to use. Many of them are completely free and open to use in pretty much any way you want to. For example, NASA has a wide variety of things available through its public API. I use one of them in Power Automate with a custom connector to post their daily image to Twitter. For my contribution to this year’s C# Advent, I will demonstrate how easily you can implement any JSON-based API into a C# based application.

C# Advent 2021 - Using C# Code in Power Automate

This post is my contribution to the C# Advent 2021. Power Automate has a fantastic feature in preview that lets you add some C# code to your flows. It requires using a custom connector, so it’s limited to those with a license that allows that. There are also a number of other limitations which I’ll get into later. But it’s a start. Yeah, I know, if you want to use C#, why not use a Logic App or Azure Function? And that’s perfectly all right (and for production apps I’d go that route right now). But this is cool, so why not? I’ve blogged before about creating custom connectors in Power Automate. I glossed over the Code tab in that post, but now it’s time to return to it.

Problem 1 For Puzzles for Day 11, we want to navigate through a cave of octopi by predicting when their bioluminescent energy will flash so we don’t disturb them. The octopi are arranged in a 10x10 grid, with each octopus represented by a power level from 0 to 9.
