Title: Understanding the Simple Art of Writing a Dynamics 365 Plugin: A Comprehensive Guide for Beginners


As the business world embraces digital transformation, the need for effective, efficient and customised IT solutions is more prevalent than ever. Microsoft’s Dynamics 365, an innovative collection of intelligent business applications, has been at the forefront of this transformation, empowering businesses to unify their CRM and ERP capabilities. For developers, writing a Dynamics 365 plugin is a crucial skill that brings about untapped potential. In this article, we will delve into a comprehensive guide on how to write a simple Dynamics 365 plugin.

Defining a Dynamics 365 Plugin:

A plugin in Dynamics 365 is a custom business logic piece that you can integrate to modify or augment the standard behaviour of the platform. Plugin development enables businesses to tailor Dynamics 365 to their precise needs, enhancing functionality and streamlining operations.

Let’s get started with understanding how to write a simple Dynamics 365 plugin.

1. Setting Up The Development Environment:

Begin by setting up a development environment for writing your Dynamics 365 plugin. Download and install Visual Studio and .NET Framework, as they are fundamental tools for Dynamics 365 plugin development. Ensure you also have the Dynamics 365 Software Development Kit (SDK) for a seamless plugin creation process.

2. Creating a New Project:

Open Visual Studio, click on ‘File’, then ‘New’ and finally, ‘Project’. Choose ‘Class Library’ under Visual C# and name your project. Upon completion, delete the class file automatically created as we’ll create our plugin class.

3. Installing NuGet Packages:

Within the Visual Studio environment, proceed to install NuGet packages for Dynamics 365 SDK assemblies. These include Microsoft.CrmSdk.CoreAssemblies and Microsoft.CrmSdk.Workflow.

4. Writing the Plugin Code:

Now, add a new class to your project, which will harbour the logic for your plugin. Write your code within the ‘Execute’ method, which gets triggered when specified events occur in the Dynamics 365 environment.

The code to write will depend on your specific business needs. However, a core point to consider is handling exceptions adequately so that any occurring errors would be tracked inside Dynamics 365.

5. Signing the Plugin:

For the plugin to work with Dynamics 365, it must be signed. Right-click on your project in Visual Studio, select properties, then go to the ‘Signing’ tab. Check the ‘Sign the assembly’ box and choose a strong name key file or create a new one.

6. Building and Registering the Plugin:

After writing and signing your plugin, build it to generate the DLL file. Once generated, we must register this DLL within’ Dynamics 365 using the Plugin Registration Tool in the SDK. The tool allows for registration of your plugin and configuration of when and where it should execute.

Testing and Debugging Plugins:

Once you’ve registered the plugin, test it thoroughly. This will help ensure your plugin works as intended and doesn’t introduce new issues into your Dynamics 365 environment. Microsoft offers robust debugging capabilities through the Plugin Profiler, allowing you to simulate and debug your plugins efficiently.

Important Points to Remember:

When writing a Dynamics 365 plugin, remember to adhere to best practices. Understand the event execution pipeline, manage exceptions correctly, avoid long-running processes that may time out, and always thoroughly debug and test your plugins.


Writing a simple Dynamics 365 plugin is a powerful way to customise your business processes, creating solutions that fit your specific requirements. The journey may seem complex initially, but with clear understanding, practice and patience, you’ll soon master the art of Dynamics 365 plugin creation.
