Many developers are building Single-Page Applications (SPAs) using popular frameworks like Angular, React or VueJS. They all come with an easy way to generate all required HTML, CSS, JavaScript and Webpack artifacts required to deploy to production, usually an NPM script like npm run build away. Having to build all those artifacts multiple times while developing on our local machine is not too pleasant, all of them come with a way to launch a development server that hot reloads artifacts when needed, usually another NPM script (such as npm run start) away.

I know, I know. That title is probably a bit too harsh and opinionated. But it got your attention, right? A friend of mine this week asked me whether they could use middleware in their HTTP-triggered Azure Functions, ideally even the same ones they use in ASP.NET Core applications. After all, the SDK comes with HTTP triggers that seem to use the same infrastructure, right? My immediate response was “whyyyyyy?!?”. And in this blog post, I’ll try to explain. via GIPHY

In 2013, I was asked to be part of a conference agenda committee. Since, I have been part of a couple more, for conferences in different parts of the world. Being “on the other side” of a Call for Papers has been very interesting, and taught me that this is a difficult job. There’s lots of reading, discussion, re-reading and more discussion involved. At some point there comes the rewarding bit of accepting sessions to the agenda, and the part I hate the most: having to reject sessions.

In an application I’m writing, I need to deserialize some JSON. I know the class to use is JsonConvert, but which NuGet package was that type in again? Granted, that’s an obvious one. Yet, there are many uses for a “NuGet reverse package search” that helps finding the correct NuGet package based on a public type.

This week, I had the opportunity to speak at NDC Oslo. The talk I did was “Indexing and searching NuGet.org with Azure Functions and Search”, which covers a story of re-building an existing service using a serverless approach, on Azure Functions. As promised, here are the slides as well as the recording. Which NuGet package was that type in again? In this session, let’s build a “reverse package search” that helps finding the correct NuGet package based on a public type.

Thanks to the folks organizing Cloud Developer Days Poland, I had the opportunity to give two talks in Krakow, Poland this week: As promised, here are the slides for both.

That was fun! I had the opportunity to present at CodeStock 2019 in Knoxville, TN (USA). The conference is for the community, by the community, which means lots of enthusiast people around. The talk I did was Exploring .NET memory management - a trip down memory lane. Slides are available below. Demo code is available from GitHub.

This week, I had the privilege to visit ConFoo Montreal for the third time. It’s a great conference that has attendees interested in lots of technologies such as PHP, Java, .NET and more. Even better: I got to deliver two talks: As promised, here are the slides for both.

The nice folks of TechDays Finland provided me with the opportunity to speak about Microservices for building an IDE - The innards of JetBrains Rider. It was nice to be able to talk about some of the internals, architecture and design decisions that were made while building a .NET IDE - Rider. If you’re interested in the slides, find them below. This story is also avilable as an article on CODE Magazine: Building a .NET IDE with JetBrains Rider.

Usually on my development machine, I run ASP.NET Core applications in Kestrel. It’s easy to do, the project templates .NET Core provide create a nice launchSettings.json to start it from the command line, etc. However, I was asked to help someone out with hosting ASP.NET Core in IIS Express. Great! The default launchSettings.json contain an entry for that as well, so I ran dotnet run --launch-profile "IIS Express".
