Title: A Simple Guide to Writing Your First Dynamics 365 Plugin


Microsoft Dynamics 365 offers a robust and versatile platform for businesses seeking to streamline their operations. Among the many features it provides, one that stands out is its support for plugins. Plugins allow you to customise, extend, and integrate with Dynamics 365 in ways that can supercharge your business processes. Today, we’re embarking on a journey to demystify the process of writing a simple Dynamics 365 plugin.

Understanding Dynamics 365 Plugin

Before we delve into the technicalities, it’s crucial to understand what a Dynamics 365 plugin is. Essentially, it’s a custom business logic that you can integrate into the Dynamics 365 system to augment its functionality. With plugins, you can react to system events or changes in data and effectively manage complex business rules.

The Prerequisites

Before you can write a Dynamics 365 plugin, you need a few tools:

– Microsoft Dynamics 365 SDK
– Visual Studio (2015 or later)
– .NET Framework 4.6.2

Step-by-Step Guide to Writing a Dynamics 365 Plugin

1. Set up the Development Environment:

First, launch Visual Studio and create a new Class Library (C#) project. Install the ‘Microsoft.CrmSdk.CoreAssemblies’ NuGet package, which will import all the necessary Dynamics 365 SDK libraries.

2. Define the Plugin Class:

You’ll need to create a public class that inherits from the IPlugin interface provided by the Dynamics 365 SDK. The IPlugin interface contains just one method: Execute. This method will be the entry point for your plugin.

3. Implement the Execute Method:

Here, you write the logic of your plugin. This method takes an IServiceProvider as an argument, which can provide instances of several helpful classes:

– IPluginExecutionContext: Provides contextual information about the plugin execution.
– IOrganizationService: Allows you to interact with Dynamics 365 data.
– ITracingService: Enables logging for your plugin.

4. Register the Plugin:

Once you effectively write and compile the plugin, you’ll need to register it in Dynamics 365 using Plugin Registration Tool in the Dynamics 365 SDK. This tool allows you to specify when your plugin should be triggered.

Best Practices for Writing Dynamics 365 Plugins

1. Always Catch Exceptions:

Exceptional error handling is crucial. Wrapping your business logic within a try-catch block will ensure that unhandled exceptions are not propagated up to the Dynamics 365 platform.

2. Use Early-Bound Classes:

It’s recommended to use early-bound classes over late-bound classes. Early-bound entities possess IntelliSense support, strong type checking, and better refactoring capabilities, making them easier to work with.

3. Use Filtering Attributes:

When registering a plugin, you can use filtering attributes to reduce the number of times your plugin executes. This approach is more efficient and minimises unnecessary operations.


Writing a Dynamics 365 plugin could appear daunting initially, but with the right understanding and practical guidance, the process becomes less complicated. From defining your plugin class to implementing the execute method and registering your plugin, each step brings you closer to customising Dynamics 365 for your unique business needs.

Remember to employ the best practices mentioned; they not only simplify the process but also optimise your plugins for better performance. As you continue to explore plugins, you’ll no doubt discover numerous ways to enhance and streamline your business processes via Dynamics 365.
