Title: A Step-by-Step Guide on Writing a Simple Dynamics 365 Plugin


Welcome to our insightful guide on creating a simple Dynamics 365 plugin. Microsoft Dynamics 365, a stellar product from the tech giant, offers businesses an avenue to unify their customer relationship management (CRM) and enterprise resource planning (ERP) capabilities. However, in order to fully customise and marshal this powerful software suite to suit various business needs, writing plugins becomes inevitable. This blog post walks you through practical steps to do just that.

Step One: Setting Up Your Development Tools

Firstly, you need to set up your development environment. Here, two significant tools are essential:

1. Visual Studio: The latest version of Visual Studio should be downloaded and installed from the official Microsoft website.

2. .NET Framework: This is a requirement for any Dynamics 365 plugin project. You need to install the .NET Framework, which acts as a software framework developed by Microsoft, running primarily on Microsoft Windows.

Step Two: Creating a New Project

Once you’ve set up these tools, launch Visual Studio and create a new project. Go to File > New > Project. Select ‘Class Library (.NET Framework)’. Name the project and select the location for the project files. Keep in mind that the name you choose will represent your entire plugin.

Step Three: Adding Microsoft Dynamics SDK References

Next, we need to add Microsoft.Xrm.Sdk.dll to the project. This DLL file contains the essential functionalities needed for Dynamics 365 plugin development. You can find it in the CRM SDK bin folder. To add it, right-click ‘References’ under the Solution Explorer, click ‘Add Reference’, and point to the DLL file.

Step Four: Writing the Plugin Code

Now it’s time to delve into some coding. Firstly, include the “Microsoft.Xrm.Sdk” namespace in your class file. This namespace contains the ‘IOrganizationService’ interface, which is essential for communicating with Dynamics 365.

A basic plugin will consist of a public class implementing the IPlugin interface found within Microsoft.Xrm.Sdk. The main process and logic of your plugin are encompassed within the Execute method.

A typical Dynamics 365 plugin might look like this:
using System;
using Microsoft.Xrm.Sdk;

public class HelloWorldPlugin: IPlugin
public void Execute(IServiceProvider serviceProvider)
IPluginExecutionContext context = (IPluginExecutionContext)

IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)

IOrganizationService service =

// Your Logic Here

Step Five: Building and Signing the Assembly

Once you’ve written the code, it’s time to build and sign the assembly. Go to Build > Build Solution to start building your project. This outputs a .dll file which represents your plugin. Then, right-click on your project, click ‘Properties’, then ‘Signing’. Check the ‘Sign the assembly’ box, select ‘‘, specify a key file name, password and confirm it.

Step Six: Registering the Plugin

After building and signing your plugin, you need to register it using the Plugin Registration Tool from the Dynamics 365 SDK. This tool uploads and links your .dll file with Dynamics 365. Launch the tool, connect to your CRM instance, click ‘Register > Register New Assembly’, then ‘browse’ to locate your .dll file and upload it.


In this guide, we’ve taken a dive into the process of writing a simple Dynamics 365 plugin. With these steps, you’re not just a reader anymore, but a creator who can mould Dynamics 365 to meet specific needs. As you learn more, you’ll be able to implement more complex functionalities and add increased value to your business operations.

Remember, the power of Dynamics 365 lies not just in its out-of-the-box functionality, but also in its customisability. Happy coding!
