Custom Activities — In the previous part, we did something really cool: we invoked a workflow in response to a domain event. And although that workflow was rather harmless, now that we have the important pieces in play we can do a whole lot more damage :) With Elsa’s increasingly rich set of…

Executing Workflows — In the previous part, we did the grunt work of setting up a basic ASP.NET Core web app project with UI, domain models and data access. We can now upload documents and store information in a database. In this part, we will see how we can invoke workflows in response…

Setting up Persistence & File Uploads — In the previous part, we learned how to configure Elsa to provide workflows from JSON files. In this part, we will return to the demo application at hand and implement the Document Upload screen. Pretty much nothing about this post is specific to Elsa, but instead it will result in…

Executing workflows from JSON files & Workflow Providers — In the previous part, we setup a solution with an ASP.NET Core web application and configured it to be an Elsa server. We’ve seen that we can design workflows with Elsa Studio that are then somehow available to our app. But how and where are these workflows stored? In this…

Scaffolding the solution — In the previous part, we introduced the sample solution we are building. In this part, we will scaffold parts of the solution up to the point where we have a basic Razor pages web app and an Elsa Server up and running that can execute workflows. File -> New Project Or, in other words: …

Introduction to the multi-part series on building workflow driven applications with Elsa and .NET — In my previous article about building workflow driven .NET Core applications with Elsa, we looked at integrating Elsa 1 into your .NET Core application. A lot has changed between V1 and V2 and the best way to get a feel for the differences is to see what it takes to…

Implementing background tasks could hardly be any simpler with ASP.NET Core today. But when it comes to scheduling background tasks, what do you do? As it turns out, you have a number of very attractive options available to you. Specifically, I’m thinking: ASP.NET Core Hosted Service Quartz.NET Elsa Workflows (the…

A brief guide on implementing Search using Orchard Core, Lucene and GraphQL. — Recently I was asked how one would go about enabling search functionality in a front-end single-page-application (SPA) that is powered by Orchard Core CMS. Now, I already knew that Orchard provides search functionality using Lucene.NET, so I figured its Lucene module probably exposes a REST API that the SPA should…
