Microsoft has significantly revolutionized business strategies and operations with its Dynamics 365. Uniting CRM and ERP capabilities, Dynamics 365 offers an integrated approach in managing business functions. But to unlock its full potential, the ability to write Dynamics 365 plugins is a vital skill. In this blog post, we will walk you through writing a simple Dynamics 365 plugin.

First Things First – Understanding Dynamics 365

Before diving into the crux of developing a plugin, it’s fundamental to understand what Dynamics 365 entails. Microsoft Dynamics 365 is a suite of intelligent business apps designed to unify CRM and ERP capabilities into one streamlined solution. It aims to boost your business performance by offering advanced AI-driven insights, comprehensive automation, and superior predictive capabilities.

What is a Dynamics 365 Plugin?

Plugins are custom business logic (code) that you can integrate into the execution of Dynamics 365 to modify or extend its standard behaviour. With the ability to trigger them on numerous events within the system, Plugins offer greater customization, ensuring workflows better align with your unique business needs.

Step-By-Step Guide to Writing a Simple Dynamics 365 Plugin

1. Setting Up the Development Environment:

First off, ensure that you have the basics sorted: Install Visual Studio and the Software Development Kit (SDK) for Dynamics 365. The SDK provides the tools, libraries, and code samples required for plugin development.

2. Creating a New Project:

Open Visual Studio, navigate to ‘File’, select ‘New’, and then ‘Project’. In the new project window, select ‘Class Library’ under ‘Visual C#’. Assign a name to your project and click on ‘OK’.

3. Adding Assemblies:

After creating a new project, add the necessary assemblies. Right-click on ‘References’ and select ‘Add Reference’. Browse to the SDK bin folder and add the ‘Microsoft.Xrm.Sdk’ assembly.

4. Writing your Plugin Code:

The next step is writing the code for your simple plugin. Make sure your plugin class implements the ‘IPlugin’ interface from ‘Microsoft.Xrm.Sdk’.

public class MyFirstPlugin : IPlugin
public void Execute(IServiceProvider serviceProvider)
// Your custom code

This code template creates a new plugin class and a method ‘Execute’ that runs when the plugin triggers.

5. Implementing your Plugin Logic:

Inside the ‘Execute’ method, you write your plugin’s custom logic. You can retrieve the context (containing event details) through the service provider to understand the trigger behind the plugin’s execution.

6. Signing the Plugin Assembly:

Before deploying, you need to sign your assembly. Right-click on the Project, select ‘Properties’, navigate to the ‘Signing’ tab, check ‘Sign the assembly’, and then ‘Create a new strong key’.

7. Building and Registering the Plugin:

Build your project by clicking on ‘Build Solution’ in the ‘Build’ menu. After building, register your plugin using the ‘Plugin Registration Tool’ in Dynamics 365.


Writing a simple Dynamics 365 plugin marks the beginning of a pathway to enhance your system’s functionality. With this instruction set, you’ll have a basic plugin up and running. As you progress, you can explore more complex scenarios, employing the boundless potential that Dynamics 365 extension truly offers.

Remember: Always code responsibly and ensure that your plugins are tested thoroughly before being deployed into the production environment. Happy plugin writing!
