Title: A Simple Guide to Writing a Microsoft Dynamics 365 Plugin

Every modern business operates with the objective of streamlining its processes, enhancing productivity, and ultimately driving growth. One tool that stands at the forefront of facilitating these goals is Microsoft’s Dynamics 365. Incorporating plugins into your Dynamics 365 ecosystem can help bring about a higher level of functionality, efficiency, and customization. In this article, we shall delve into a simplified guide on writing a Microsoft Dynamics 365 Plugin.

A plugin is essentially a custom business logic that integrates seamlessly with the Dynamics 365 platform to modify or augment the standard behaviour of the system. Development of these plugins requires a basic understanding of C# or .NET. Thus, before embarking on writing a Dynamics 365 plugin, it’s best to familiarize yourself with these programming languages.

**Understanding Dynamics 365 Plugin Architecture**

Microsoft Dynamics 365 utilises an event-driven architecture for plugins. Each operation in the system triggers specific events as either pre-events (before the primary operation) or post-events (after the operation). Plugins can interact with these events, thus making them powerful tools for modifying system behaviour.

**Prerequisites for Plugin Development**

Before getting started with plugin development, ensure you have the following:

1. **Visual Studio:** This tool allows you to write, edit and test your code. It supports numerous languages, including C# which we’ll be using.
2. **.NET Framework:** As Dynamics 365 is built on .NET, your plugin also needs to be.

**Steps to Write a Dynamics 365 Plugin**

Let’s break down the process into simple steps:

**Step 1: Setup your project in Visual Studio**

Launch Visual Studio and create a new Class Library project. Ensure you select .NET Framework as the type and input an appropriate name.

**Step 2: Add the necessary references**

To interact with Dynamics 365, your plugin needs to reference Microsoft.Xrm.Sdk.dll. To add this, right-click on “References” in your project, then click on “Add Reference”, and browse for the DLL.

**Step 3: Writing the Plugin Code**

Here’s a rudimentary plugin code example:

public class MyPlugin : IPlugin
public void Execute(IServiceProvider serviceProvider)
// Obtain the execution context from the service provider.
IPluginExecutionContext context = (IPluginExecutionContext)

// Do some work here…

This is a basic structure of a Dynamics 365 plugin. The `Execute` method is where you place the code to run when the plugin is triggered.

**Step 4: Register the plugin**

After writing and compiling the plugin, you need to register it within Dynamics 365. Use the Plugin Registration Tool provided by Microsoft for this. Open the tool, connect to your Dynamics 365 server, and register a new assembly.

When registering, you’ll also define the triggering points for your plugin (i.e., what specific operation on which entity will trigger your plugin). After these steps, your plugin is ready to enhance your Dynamics 365 experience!


Writing a Dynamics 365 plugin may seem like a daunting task initially, but once you grasp the core concepts, it becomes an efficient way to customize your CRM and meet unique business requirements. Always remember to thoroughly test your plugin in a non-production environment before deploying it to live. Happy coding!
