Learn how to create dynamic Open Graph profile images using C# and .NET in this step-by-step guide.

I’ve been streaming ‘Coding with JoeG’ on Twitch for a few months now. The general theme of the stream is teaching software development with C#. We’ve been building a contact management application to demonstrate some best practices. About two weeks ago, or so, I added an Azure Storage Blob Container to hold the images of the contacts. I did this using the way I knew how to do it using Storage Access Keys and a library, JosephGuadagno.AzureHelpers.Storage, that I wrote to make it ‘easier’ to interact with Azure Storage. While talking about the stream on Twitter, Christos, PM on the Microsoft Identity team, reached out and said I should try securing the Container/Blob with Managed Identity. I tried on the stream for a good 5 or so hours and could not get it to work. If you want to see it, check out the recording of the stream on my YouTube channel.

In this post, we’ll walk through how you can use Azure Key Vault to secure sensitive settings in Azure Functions. If you don’t have a Key Vault setup, I covered setting one up in the post titled ‘Setup Code Signing Certificates in Azure Key Value’

Deciding between .NET MAUI and Uno? This practical guide breaks down platform reach, UI consistency, and complex workflows.

There has been much talk on social media about being a Software Engineer/Developer/Programmer in the last week or so, probably because we are all being safe and staying in our houses with not much else to do. Conversations have included what it takes to be an engineer, how to get started in engineering, and explaining what a ‘Software Engineer’ does.

When using Google or Bing Maps to lookup an address or point of interest, both display address suggestions in a user-friendly way. In the example below, I type “Time Square”, and Bing suggests a few addresses/places.

I was chatting with Dave Brock (@daveabrock) about our .NET 5 presentations today (.NET 5 - What is it?). He mentioned that he wanted to “steal” my PowerPoint embed feature. Dave’s a nice guy and all but is it really stealing if you ask for it? :smile:

It’s time to take your unit testing to the next level. You’ve implemented either NUnit, or xUnit, or MSTest in your projects. You’ve gotten your code coverage to 80+%. But the are just some things that are hard to test or validate in your project. How do you test the “business logic” in your repository class? How do you test your dependent web service or database? Yeah, you can write special unit test and create fake objects to mimic these dependencies but why waste your time writing code that does not ship with the end product. Or write a lot of code with the ExcludeFromCoverage attribute :smile:. Well this is mocking comes in.

While I was presenting my workshop Building and Deploying a New Cloud App from Scratch at DEVIntersections yesterday the connection to the database kept failing. Which was weird because I’ve gone through the code quite a few times to make sure everything worked. The good thing is that it failed during the creation of the integration tests which demonstrated the benefit of creating them. However, that did not help me on stage. I was getting the following error:

In a previous post, I showed you how to Setup Code Signing Certificates in Azure Key Vault. In this post, I will show you how to create an Extended Validation (EV) Code Signing Certificate with digicert and store it in Azure Key Vault.

For the past few weekends, I’ve been working rebuilding a library I wrote to make it easier to use Azure Storage. I started this library about 4 or 5 years ago, and it did not have ‘true’ unit tests. I’m not going to talk about what makes a good unit test and what doesn’t. There are plenty of posts around that! I decided to rewrite all of the tests and move to xUnit. After creating about the 50th test or so, I noticed a pattern in the initial shell of the tests. Most of the tests looked like this.

A year ago, yesterday, I went to the Emergency Room because I was getting cold sweats, and something did not feel right with my body. Well, after a few tests and a few doctors later, a cardiologist came in and told me I had 90% blockage in the left anterior descending artery, better known as the Widow Maker. It’s known as the widow maker because you tend to have minutes left to live when it is blocked. I am glad I listened to my body and my wife and went into the Emergency Room.

Securing our applications and data is critical in this day and age. I’ve been working a lot with the new Microsoft identity platform (MSAL) library, so I decided to create a series of blog posts around working with it.
