The method returns the sum of all digits in the input argument. The following screenshot shows the Studio app flow for this example: ![Studio Flow diagram with Listener, Execute operation, and two Transform Message components](/mulesoft/current/en-us/microsoft-dotnet-connector/latest/_images/microsoft-dotnet-use-case.png) 1. Create a new Mule project in Studio. 2. In the **Mule Palette** view, search for `http` and select the **Listener** operation. 3. Drag the **Listener** operation onto the Studio canvas. 4. In the **Listener** configuration, click **+** next to the **Connector configuration** field to add a global element. 5. Set the **Host** field to `localhost`. 6. Click **OK**. 7. In the **Listener** configuration, set the **Path** field to `sumOfDigits`. 8. From the **Mule palette** view, drag a **Transform Message** component to right of **Listener**. 9. Click **Transform Message** and set the output as follows: ```dataweave dw 2.0 output application/json --- {number: payload.num } ``` This code sets the input argument for the method to execute. It obtains the `num` param from the payload and assigns it to a new variable called `number`. 10. In the **Mule Palette** view, search for `dotnet` and drag the **Microsoft DotNet** > **Execute** operation onto the Studio canvas, to the right of **Transform Message**. 11. In the **Execute** operation configuration, click **+** next to the **Connector configuration** field to add a global element. 12. In the **Scope** field, select `Singleton`. 13. Click the **Assembly** tab and enter `DemoDotNet.dll` in the **Path** field. 14. Click **OK**. 15. In the **Execute** operation configuration, enter the following metadata in the **Type** field: `DemoDotNet.NumberLibrary, DemoDotNet, Version=1.0.0.0, Culture=neutral, PublicKeyToken=PUBLIC_KEY_TOKEN` This metadata specifies information about the .NET library to use. Once the connection is established, the connector retrieves the metadata and populates the **Method info** section, which contains all of the methods exposed by the `DemoDotNet.dll` library. This example shows the `SumOfDigits` method, which receives the number defined in the payload of the **Transform Message** component: `DemoDotNet.NumberLibrary, DemoDotNet, Version=1.0.0.0, Culture=neutral, PublicKeyToken=PUBLIC_KEY_TOKEN | SumOfDigits(System.Int32 number) → System.Int32` 16. From the **Mule palette** view, drag a second **Transform Message** component to right of **Execute**. 17. Click **Transform Message** and set the output as follows to transform the result of the **Execute** operation to Java: ```dataweave dw 2.0 output application/json --- payload ``` 18. Save the project. 19. Test the app by sending a REST request to `localhost:8081/sumOfDigits`. ## Use Case XML Paste this code into your Studio XML editor to quickly load the flow for this example into your Mule app: ```xml ``` ## See Also - [Introduction to Anypoint Connectors](https://docs.mulesoft.com/connectors/introduction/introduction-to-anypoint-connectors) - [Salesforce Help](https://help.salesforce.com)
