ELSA Workflow (14)

ELSA is a workflow engine for .NET Core. It is a library that can be used to build workflow applications. It is also a standalone application that can be used to run workflows.

It is included in this ASP.NET Core samples repository because I believe that a workflow engine can play a very substiantial role in the future of ASP.NET Core applications.

Activities

• WriteLine Activity

  This sample demonstrates a very simple workflow Activity that writes a line to the console.

• Sequence Activity

  This sample demonstrates the Sequence activity. The Sequence activity is a container activity that contains other activities. The Sequence activity executes the activities in the order they are added to the workflow.

• If Activity

  This sample demonstrates the If activity. The If activity is a container activity that contains two activities. The first activity is executed if the condition is true. The second activity is executed if the condition is false.

• SetVariable Activity

  This sample demonstrates the SetVariable activity. The SetVariable activity is used to set a variable in the workflow.

• While Activity

  This sample demonstrates the While activity. The While activity has a Condition property that is used to specify the condition on when the workflow continues to be executed.

• For Activity

  This samples demonstrates the For activity. We use For activity to execute a workflow in a loop within specified parameters.

• ForEach Activity

  This samples demonstrates the use of ForEach activity. We use ForEach activity to execute a workflow in a loop based on a given collection.

• Composite Activity

  Composite Activity is a way to encapsulate a set of activities into a single activity.

• Fork Activity

  Fork Activity allows you to split a workflow into two or more branches, each with its own set of actions. All the branches in the workflow must be completed before the worfklow con continue to the next step after the fork.

• Fork Activity 2

  This sample demonstrates on how to set and use variables in a fork activity.

Workflow

• Workflow with variables

  This sample demonstrates on how to create a custom workflow and pass a variable to it.

• Workflow custom properties

  This sample shows how to set up custom properties for a workflow. We also use the basic workflow properties such as DefinitionId, Description, etc.

• Workflow that return result

  This sample demonstrates on how to create a workflow that returns result.

• Workflow with runtime inputs

  This sample demonstrates on how to create a workflow that take runtime inputs.

• Workflow data via constructor

  This sample demonstrates on how to pass values to a workflow via constructor.
