.NET Core WebJob Console app CI/CD using Azure DevOps Pipelines

.NET Core WebJob Console App CI/CD using Azure DevOps Pipelines Background WebJobs is a feature of Azure App Service that enables you to run a program or script in the same context as a web app, API app, or mobile app as per Microsoft Document. If you build your WebJob Console app in .NET Framework then its very easy to build and deploy the WebJob with the parent API or Web App as by linking it to Web/Api App as below - The above linkage of WebJob console application with parent Web/API app is not supported by design in .NET Core. So what do we do ? In this Article we are going to see how we can build a .NET Core WebJob Console app separately from the parent Web/API…

WSL2 for Dockerized .NET Core application

Build Containerised .NET Core Application using Docker on Windows Subsystem for Linux (WSL) 2 When first Windows Subsystem for Linux (WSL) launched, I tried to use it as a Linux development platform and ran my first Cross Platform .NET Core Web Application and I found it amazing. With the popularity of Microservices, containerised applications with Docker is one of the hottest topic in the market. While learning this piece of tech I thought of using my WSL to use it as my Docker development platform natively on experimental basis.While doing many failed attempts to install and trying to configure Docker in WSL1, Microsoft announced the release of WSL2 on their 2019 Build conference.Also, it was announced that a full-blown Linux Kernel is shipping with Windows 10. Naturally my expectation for…

Azure DevOps – manage your application lifecycle in cloud

Manage your Application's lifecycle in Cloud using Azure DevOps Infographic : Application Lifecycle Management in Azure DevOps What is Application Lifecycle Management (ALM) ? Application lifecycle management (ALM) is the product lifecycle management of computer programs. It encompasses requirements management, software architecture, computer programming, software testing, software maintenance, change management, continuous integration, project management, and release management. [Source wikipedia.] An ALM tool should have the capability to maintain all the aspects of a software lifecycle, such as capturing the ideas, users requirement, planning of work, maintaining source code, deploying code using continuous integration and continuous delivery (CI/CD). It should also provide real time project insights to the key stake holders of a project. We can think of an ALM software as one stop shop for a software project/product management as a…

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…

SQL Server on Linux – Install and use it with SQL Operations Studio

SQL Server 2017 on Linux - install database engine and manage it using cross platform SQL Operations Studio. As we already know that Microsoft loves Linux and similarly SQL Server also fell in love with Linux. On October 2017 Microsoft announced the general availability of SQL Server 2017 for Linux. This relationship brought us many goodness in the table. This gives us freedom of Platform of our choice, unprecedented security of Linux, pricing of opensource with all great features, this are just few examples. Few of the studies also found that moving secondary databases to Linux paid for itself in less than nine months. Now you can imagine the possibilities of this movement.To bring the SQL Server on Linux experience - in continuation of my previous post, in this post…

Windows Subsystem for Linux – build ASP.NET Core MVC web app in Linux

Build Cross Platform ASP.NET Core MVC Web application in Windows subsystem for Linux. Have you ever imagined of running .NET in Linux? it sounded like a crazy idea or a wildest dream of a Microsoft stack developer up until a couple of years ago. But not anymore... this is a reality now. With Windows Subsystem for Linux (WSL) in Windows 10 we can do many crazy things, one of such thing is running .NET applications inside Linux (yes your wildest dream is not a dream anymore, it's a reality now).Today we are going to witness one of such things by building a ASP.NET Core MVC web application in Linux. We are going to install .NET Core in native Ubuntu installation. Will build a MVC web application and then run it…

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…

Microsoft Loves Linux – what it means to you and your clients?

Microsoft's new open philosophy - see how you can help your clients. 'Microsoft loves Linux' - yes you read it right. There was a time when Linux was compared with Cancer once. The scenario has totally changed. Now they are kind of in a romantic relationship. If you have followed some recent announcements by Microsoft in Satya Naddela era, they are really focused on making things open source, making things cross platform, building things for Cloud and Mobile first world. Few years ago, we got .NET Core - a modular, high performing light weight .NET framework to build cross platform applications targeting Windows, Linux and MacOS. Which enabled us modernising the application in the era of client side heavy, modular, containerised applications built for cloud and obviously targeting operating system of…
