.NET 6 Azure Web App Deployment using Azure DevOps Pipelines

.NET 6 Azure Web App Deployment using Azure DevOps Pipelines This is the Summer of 2021, and Summer means a ton of new announcements and public previews of cool stuff from Microsoft to play with. This summer a few things are on my radar and, I’m really excited about the possibility. First and foremost, .NET 6 with C# 10 (I can see the future lies here). Visual Studio 2022 and finally Windows 11. I got my personal development machine updated last weekend. To put everything into a test, I wanted to write a piece of code in .NET 6 (a Minimal API) with C# 10 in Visual Studio 2022 IDE on Windows 11, test it on Linux (WSL2).

Hosting Free Website with Serverless backend on Azure Static Web App

Hosting Free Website with Serverless backend on Azure Static Web App If you are looking for a cost-optimised website deployment (or may be a free web hosting) in Azure then this is for you. A couple of years ago I found a technique of hosting static Websites in Azure that costs only a Dollar (I call it One Dollar Deployment). This was using Azure Storage’s static website. In Build 2020, Microsoft announced Azure Static Web App with a Serverless Backend. This was different than my Azure Storage’s static website. It was fully managed and automated using GitHub actions. I was excited about the possibilities of it but wasn’t happy that it supported GitHub actions only for deployment. After almost a year, Azure Static Web App started supporting Azure DevOps in Public…

Inner Source – the key to improving software asset reusability

Inner Source - the key to improving software asset reusability Some background first Can you afford to re-invent the wheel? I’m sure most of you will say a big NO. Similarly, in software development, it’s not very common to build a piece of software from scratch unless you are building something which was not done by anyone before you in the world. Typically, a development team gets help from a platform like GitHub, or get help from other similar projects running within your organization. They copy the base code (let’s call it the initial codebase) from others and start developing on top of that. This is re-using the wheel.This is one way of looking at re-usability, since they have re-used someone else’s code. When we talk about improving the re-usability of software…

Document Versioning with Azure Blob Storage

Document Versioning With Azure Blob Storage Some Background First Almost all organizations have a need for document storage for their applications. If the organization is a Microsoft shop then, one of the most popular choices for them is SharePoint Document Library. SharePoint Document library allows you to store documents, retain their versions, provides the ability to make any old version to the current version, last but not the least deleting a specific version of a document. With all the goodness of SharePoint, it comes with its own limitations. For many custom cloud applications build, SharePoint may not always be the right choice because of various reasons. It needs a dedicated setup, licensing etc. And just to use the document library feature, the investment may not always be justifiable. So, what…

Make your .NET Core HTTP endpoint to react to Custom Azure Event Grid Events

Custom Azure Event Grid event handling with .NET Core WebHook Some background first In todays Cloud first world Event Driven Architecture (EDA) and reactive programming are gaining a lot of traction in Microservices architecture design and development paradigm. In the event driven architecture scenario WebHook plays a huge role doing various stuffs in a reactive manner with Pub-Sub model. When a HTTP endpoint responds to a request (instruction) and does some stuffs like GET, POST, DELETE then we can safely call it API, but when a HTTP endpoint responds on it's own when certain event occurs then we can call it a WebHook. For a WebHook to respond to certain events it has to subscribe to an event publisher with it's HTTP endpoint URL. In the current context WebHook is the subscriber of…

Run native Linux bash on Windows 10

Native Linux on Windows 10? Yes! it's real. Let's see how. Remember those old days when we had to use Linux’s VI editor to write C, C++ , Java code in our School/ College days? Do you also remember how we used to get that black UNIX terminal (Bash) in our Windows machine? Well…mostly we had to do telnet from our Windows system to the Linux server to get the terminal back so that we can use the VI editor and write some code.I can remember in our programming lab we had a Linux server and it was connected to multiple Windows terminal. We used to telnet to the Linux Server to run the Bash and form there all other subsequent commands. If anyone wanted to configure a standalone system on their…
