Why Building a Plugin Base Class Makes Dataverse Plugins Better

Code-first C# plugins give you more control and flexibility than low-code tools. When you write Dataverse Plugins from scratch, you often repeat the same code. Many developers feel frustrated when frameworks do not match their own style or needs. You can solve these problems by creating your own Plugin Base Class. This approach makes your work smoother and helps you focus on real business logic.

Key Takeaways

• Making a Plugin Base Class helps you write less code. This saves time and lowers mistakes in Dataverse Plugins.

• A base class gives your code a clear layout. This makes it easier to read and understand. New team members can learn faster.

• A base class makes testing easier. It sets up all plugins the same way. You can spend more time on business logic.

• Using best practices, like good error handling and security checks, keeps plugins safe and working well.

• If you build your own base class, you control your code. You can change it to fit your team's needs.

Why Dataverse Plugins?

Server-Side Logic

Dataverse Plugins let you use strong server-side logic. This keeps your business rules safe and the same for everyone. Server-side logic works on the Dataverse server. It does not matter what device or app people use. Everyone gets the same results, and your rules always work.

Here is a table that explains why server-side logic is important:

Dataverse Plugins help you automate tasks and keep your data safe. When you write plugins, your rules run every time, no matter how someone uses Dataverse. This means fewer errors and better data.

Beyond Low-Code

Low-code tools like Power Automate and Business Rules help you build things fast. But they cannot do everything. Sometimes, low-code plugins are slower than code-first plugins. For example, PowerFX low-code plugins can be about 20% slower than C# plugins. This can be a problem if you need things to work quickly and well.

Here are some reasons why developers pick Dataverse Plugins instead of low-code tools:

Low-code tools may not let you use advanced features like local variables or arrays. Sometimes, low-code plugins do not work right or cannot do everything you want. If you need full control and speed, Dataverse Plugins are the best choice.

Common Pain Points

Repetitive Code

When you make Dataverse Plugins, you do the same steps a lot. You set up service objects, check input, and handle errors every time. Doing this over and over slows you down. It also makes your code messy and hard to read. You might copy and paste code blocks, which can cause mistakes. If you change something, you must update it everywhere.

Tip: Doing the same code many times can cause bugs and makes plugins harder to fix.

Here are some things you do again and again in Dataverse Plugins:

• Checking if input data is correct

• Setting up context and service objects

• Writing down errors and exceptions

• Doing security checks

The table below shows how these repeated jobs can be a problem for developers:

Maintenance Challenges

It is hard to keep Dataverse Plugins working well. As your system gets bigger, plugins are harder to handle. Complicated data models and many-to-many links make things confusing. You must update many parts when you change something. As you get more data, plugins can slow down. You spend more time fixing and testing them.

Moving plugins to new places can break things if you miss a step. Documentation is often behind because the Power Platform changes fast. You use help from the community, but it is not always the same.

• Complicated plugin trees make updates slow and risky.

• Hard logic needs custom plugins, which must be tested well.

• Security needs extra care in every place you use plugins.

• Connecting to other systems adds more things to watch.

Note: Keeping plugins working gets harder as your system grows. A small change can mess up many plugins and tables.

You need a better way to handle your code and make things easier. Making a Plugin Base Class helps you keep your code neat and simple to fix.

Plugin Base Class Benefits

Code Reuse

When you make Dataverse Plugins, you often repeat setup steps. A plugin base class lets you keep shared code in one spot. You can use this code in every plugin you build. This saves time and helps you make fewer mistakes. You do not have to copy setup or error code each time. Instead, you write these steps once in your base class. Every new plugin you make can use this shared code.

Here are some ways a plugin base class helps you reuse code:

• It sets up services for you

• It keeps error logs in one place

• It checks security rules in one spot

• It makes checking input easier

Tip: Code reuse means you fix bugs in one place. You do not have to update the same logic everywhere.

Cleaner Structure

A plugin base class gives your Dataverse Plugins a clear structure. You follow the same pattern for every plugin you write. This makes your code easy to read and understand. With a base class, you know where to find important logic. You can see what each plugin does without looking through repeated code.

The table below shows how a base class makes your code cleaner:

When you use the same setup, your team can work faster. New team members can learn your codebase quickly. You avoid confusion and keep your project simple to manage.

Easier Testing

Testing Dataverse Plugins is hard if each one looks different. A plugin base class gives all plugins the same setup. You can focus on testing your business logic, not the setup code. The base class takes care of things like logging and context. This makes your tests easier and more reliable.

A single structure means you can write tests that work for many plugins. You do not need new test setups for each one. You spend less time fixing tests and more time making sure plugins work right.

Note: Using a plugin base class makes testing and fixing plugins much easier. You can trust your shared code works the same in every plugin.

Build Your Plugin Base Class

Key Components

When you make your own plugin base class, your plugins get easier to use. You should focus on the steps that happen in every plugin. This saves time and helps you not make mistakes.

Here are the main parts you need:

• Service Setup: Set up things like IPluginExecutionContext and IOrganizationService. This lets each plugin get the data it needs.

• Error Handling: Handle errors in one spot. This keeps plugins safe and makes fixing problems easier.

• Logging and Tracing: Add tracing where it matters. This helps you find problems fast.

• Input Validation: Make sure input data is right before your logic runs.

• Security Checks: Check if users have the right permissions before they change anything.

Tip: If you put these steps in your base class, you only write them once. Every plugin you make can use them.

You can also add extra methods to SDK classes. These methods help you work with requests and responses faster. For example, you can use methods on OrganizationRequest and OrganizationResponse to set parameters quickly. You can also use methods on IOrganizationService for things like Create, Retrieve, and Update. These shortcuts make your code easier and faster to write.

Best Practices

You want your plugin base class to be simple to use and fix. Here are some best practices that skilled developers follow:

1. Naming Conventions: Pick clear names for your classes and methods. Good names show what the plugin does or when it runs.

2. Code Structure: Keep your files and folders organized. Put related plugins together. This helps your team find things fast.

3. Logging Practices: Add tracing at important spots in your code. This makes it easier to find bugs and see what happened.

4. Stateless Design: Keep your base class stateless. Do not store data in fields that last between plugin runs. This stops memory leaks and keeps plugins working well.

5. Proper Error Handling: Always handle errors by throwing an InvalidPluginExecutionException. This makes sure Dataverse rolls back changes if something goes wrong.

6. Security Awareness: Check user permissions before making changes. This keeps your data safe and avoids mistakes.

Note: Do not store big data or use stateful properties in your base class. Plugins run in a shared space with little memory. Keeping your class stateless helps stop crashes and memory leaks.

Example Structure

You can follow these steps to make your own plugin base class:

1. Look at your plugins. Find code that repeats, like service setup or error handling.

2. Make a new class called PluginBase that uses the IPlugin interface.

3. Move the repeated code into this base class.

4. Add a constructor that calls the base class with the current class type.

5. Override a method, like ExecuteDataversePlugin, to hold your plugin logic.

6. Use helper methods for things like input validation or security checks.

7. Add extra methods to SDK classes for common actions.

8. Register your plugin assembly and steps in Dataverse.

Here is a simple example of what your base class could look like:

public abstract class PluginBase : IPlugin
{
    public void Execute(IServiceProvider serviceProvider)
    {
        var context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
        var serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        var service = serviceFactory.CreateOrganizationService(context.UserId);

        try
        {
            ExecuteDataversePlugin(context, service);
        }
        catch (Exception ex)
        {
            // Log error and throw for Dataverse to handle
            throw new InvalidPluginExecutionException("An error occurred in the plugin.", ex);
        }
    }

    protected abstract void ExecuteDataversePlugin(IPluginExecutionContext context, IOrganizationService service);
}

You can then make a plugin that uses this base class:

public class CaseClassificationPlugin : PluginBase
{
    protected override void ExecuteDataversePlugin(IPluginExecutionContext context, IOrganizationService service)
    {
        // Your business logic here
    }
}

You can also add extra methods to make your code even cleaner:

public static class OrganizationServiceExtensions
{
    public static Entity RetrieveRequired(this IOrganizationService service, string entityName, Guid id, ColumnSet columns)
    {
        var entity = service.Retrieve(entityName, id, columns);
        if (entity == null)
            throw new InvalidPluginExecutionException($"{entityName} with ID {id} not found.");
        return entity;
    }
}

Callout: Extra methods help you write less code and avoid mistakes. You can use them for common jobs like getting or updating records.

By following these steps and best practices, you make your plugins easier to write, test, and fix. You also avoid common mistakes, like memory leaks or bad error handling. This way, you and your team can build better solutions in Dataverse.
