Unlocking the Potential of Dynamics 365: A Comprehensive Guide to Writing Your First Plugin

Title: Mastering the Art of Writing a Simple Dynamics 365 Plugin


Exploring Dynamics 365, Microsoft’s unified Customer Relationship Management (CRM) and Enterprise Resource Planning (ERP) suite, can open boundless opportunities for businesses. This remarkable cloud-powered platform offers sophisticated tools for sales, finance, service, and operations. One of its powerful features is the capacity to extend its functionalities through plugins. In this article, we’ll delve into the intricacies of writing a simple Dynamics 365 plugin to help you maximise your experience with this versatile suite.

What is a Dynamic 365 Plugin?

A Dynamics 365 plugin can be described as a set of custom .NET assembly classes designed to supplement the functionality of the system. Plugins are registered in the CRM and are triggered by specific events like create, update, and delete functions. They offer the ability to execute complex business logic rules, enabling a virtual kaleidoscope of possibilities to enhance the CRM’s usability.

Key Ingredients to Write a Dynamics 365 Plugin

Here are the main components needed to build a seamless Dynamics 365 plugin:

1. Microsoft Visual Studio: A comprehensive development environment where the plugin will be written.
2. .NET Framework: A software framework developed by Microsoft, which runs primarily on Microsoft Windows.
3. Internet Information Services (IIS): An extensible web server created by Microsoft for use with the Windows NT family.

Writing Your First Dynamics 365 Plugin: A Step-By-Step Guide

1. Setup: Begin by installing and setting up Microsoft Visual Studio on your computer. Also, ensure you have IIS installed and running effectively on your machine.

2. Create a New Project: Open Visual Studio and click on “File > New > Project”. Choose ‘Class Library’ project and name it appropriately. Ensure that the .NET Framework version is compatible with your CRM instance.

3. Reference Assemblies: Add references to the assemblies required for writing the plugin. You can find them in the CRM SDK bin folder. The most common ones are “Microsoft.Xrm.Sdk.dll” and “Microsoft.Crm.Sdk.Proxy.dll”.

4. Write the Code: Begin by writing your plugin code within the ‘Class1.cs’ file. The code will interact with the Dynamics 365 environment. This involves processing data, making logical decisions based on the input, and returning the result back to the CRM.

5. Debug: Attach the debugger to the plugin registration tool, set breakpoints in your code and begin debugging to ensure your code runs smoothly. The debug process allows you to locate and correct any issues in your code.

6. Register the Plugin: After debugging and finalising your plugin, the next step is registering it using the ‘Plugin Registration Tool’. This tool helps you register and manage your plugins, steps, images, and configurations.

Testing Your Plugin

Once the plugin has been registered successfully, test it out. This can be done by triggering the event on which your plugin was supposed to execute. Monitor the system jobs in case of any failures and view the trace log for more detail in case of a failure.


Writing a simple Dynamics 365 plugin might seem daunting initially, but once you familiarise yourself with the process, it becomes an exciting and fulfilling task. Plugins empower businesses to extend and customise their CRM efficiently, resulting in enhanced productivity and operational efficiency. So, dive into the world of Dynamics 365 plugin creation and experience the transformation first-hand.

Remember, while plugins are powerful tools, they should be used judiciously. Misuse or overuse can lead to system performance issues. Therefore, always plan your plugins carefully, considering the overall design and architecture of your CRM.

There’s no limit to what you can achieve with the right mix of knowledge, patience, and practice. Happy plugin writing!
