Manage logic apps with Visual Studio

Although you can create, edit, manage, and deploy logic apps in the Azure portal, you can also use Visual Studio when you want to add your logic apps to source control, publish different versions, and create Azure Resource Manager templates for various deployment environments. With Visual Studio Cloud Explorer, you can find and manage your logic apps along with other Azure resources. For example, you can open, download, edit, run, view run history, disable, and enable logic apps that are already deployed in the Azure portal. If you're new to working with Azure Logic Apps in Visual Studio, learn how to create logic apps with Visual Studio.

Important

Deploying or publishing a logic app from Visual Studio overwrites the version of that app in the Azure portal. So if you make changes in the Azure portal that you want to keep, make sure that you refresh the logic app in Visual Studio from the Azure portal before the next time you deploy or publish from Visual Studio.

Prerequisites

Find your logic apps

In Visual Studio, you can find all the logic apps that are associated with your Azure subscription and are deployed in the Azure portal by using Cloud Explorer.

  1. Open Visual Studio. On the View menu, select Cloud Explorer.

  2. In Cloud Explorer, select Account Management. Select the Azure subscription associated with your logic apps, and then select Apply. For example:

    Select "Account Management"

  3. Based on whether you're searching by Resource Groups or Resource Types, follow these steps:

    • Resource Groups: Under your Azure subscription, Cloud Explorer shows all the resource groups that are associated with that subscription. Expand the resource group that contains your logic app, and then select your logic app.

    • Resource Types: Under your Azure subscription, expand Logic Apps. After Cloud Explorer shows all the deployed logic apps that are associated with your subscription, select your logic app.

Open in Visual Studio

In Visual Studio, you can open logic apps previously created and deployed either directly through the Azure portal or as Azure Resource Group projects with Visual Studio.

  1. Open Cloud Explorer, and find your logic app.

  2. On the logic app's shortcut menu, select Open with Logic App Editor.

    Tip

    If you don't have this command in Visual Studio 2019, check that you have the latest updates for Visual Studio.

    This example shows logic apps by resource type, so your logic apps appear under the Logic Apps section.

    Open deployed logic app from Azure portal

    After the logic app opens in Logic Apps Designer, at the bottom of the designer, you can select Code View so that you can review the underlying logic app definition structure. If you want to create a deployment template for the logic app, learn how to download an Azure Resource Manager template for that logic app. Learn more about Resource Manager templates.

Download from Azure

You can download logic apps from the Azure portal and save them as Azure Resource Manager templates. You can then locally edit the templates with Visual Studio and customize logic apps for different deployment environments. Downloading logic apps automatically parameterizes their definitions inside Resource Manager templates, which also use JavaScript Object Notation (JSON).

  1. In Visual Studio, open Cloud Explorer. Find and select the logic app that you want to download from Azure.

  2. On that app's shortcut menu, select Open with Logic App Editor.

    Tip

    If you don't have this command in Visual Studio 2019, check that you have the latest updates for Visual Studio.

    The Logic App Designer opens and shows the logic app. To review logic app's underlying definition and structure, at the bottom of the designer, select Code View.

  3. On the designer toolbar, select Download.

    Select "Download"

  4. When you're prompted for a location, browse to that location and save the Resource Manager template for the logic app definition in JSON (.json) file format.

    Your logic app definition appears in the resources subsection inside the Resource Manager template. You can now edit the logic app definition and Resource Manager template with Visual Studio. You can also add the template as an Azure Resource Group project to a Visual Studio solution. Learn about Azure Resource Group projects for logic apps in Visual Studio.

To build logic apps for business-to-business (B2B) enterprise integration scenarios, you can link your logic app to a previously created integration account that exists in the same region as your logic app. An integration account contains B2B artifacts, such as trading partners, agreements, schemas, and maps, and lets your logic app use B2B connectors for XML validation and flat file encoding or decoding. Although you can create this link by using the Azure portal, you can also use Visual Studio after meeting the prerequisites, and your logic app exists as a JSON (.json) file inside an Azure Resource Group project. Learn about Azure Resource Group projects for logic apps in Visual Studio.

  1. In Visual Studio, open the Azure Resource Group project that contains your logic app.

  2. In Solution Explorer, open the .json file's shortcut menu, and select Open With Logic App Designer. (Keyboard: Ctrl+L)

    Open logic app's .json file with Logic App Designer

    Tip

    If you don't have this command in Visual Studio 2019, check that you have the latest updates for Visual Studio.

  3. To make sure that the Logic App Designer has focus, select the designer's tab or surface so that the Properties pane shows the Integration Account property for your logic app.

    Properties pane shows the "Integration Account" property

  4. Open the Integration Account list, and select the integration account that you want to link to your logic app, for example:

    Open "Integration Account" property list

  5. When you're done, remember to save your Visual Studio solution.

When you set the Integration Account property in Visual Studio and save your logic app as an Azure Resource Manager template, that template also includes a parameter declaration for the selected integration account. For more information about template parameters and logic apps, see Overview: Automate logic app deployment.

Refresh from Azure

If you edit your logic app in the Azure portal and want to keep those changes, make sure that you refresh that app's version in Visual Studio with those changes.

  • In Visual Studio, on the Logic App Designer toolbar, select Refresh.

    -or-

  • In Visual Studio Cloud Explorer, open your logic app's shortcut menu, and select Refresh.

Refresh logic app with updates

Publish logic app updates

When you're ready to deploy your logic app updates from Visual Studio to Azure, on the Logic App Designer toolbar, select Publish.

Publish updated logic app

Manually run your logic app

You can manually trigger a logic app deployed in Azure from Visual Studio. On the Logic App Designer toolbar, select Run Trigger.

Manually run logic app

Review run history

To check the status and diagnose problems with logic app runs, you can review the details, such as inputs and outputs, for those runs in Visual Studio.

  1. In Cloud Explorer, open your logic app's shortcut menu, and select Open run history.

    Open run history

  2. To view the details for a specific run, double-click a run. For example:

    Detailed run history

    Tip

    To sort the table by property, select the column header for that property.

  3. Expand the steps whose inputs and outputs you want to review, for example:

    View inputs and outputs for each step

Disable or enable logic app

Without deleting your logic app, you can stop the trigger from firing the next time when the trigger condition is met. Disabling your logic app prevents the Logic Apps engine from creating and running future workflow instances for your logic app. In Cloud Explorer, open your logic app's shortcut menu, and select Disable.

Disable your logic app

Note

When you disable a logic app, no new runs are instantiated. All in-progress and pending runs will continue until they finish, which might take time to complete.

To reactivate your logic app, in Cloud Explorer, open your logic app's shortcut menu, and select Enable.

Enable your logic app

Delete your logic app

To delete your logic app from the Azure portal, in Cloud Explorer, open your logic app's shortcut menu, and select Delete.

Delete your logic app

Note

When you delete a logic app, no new runs are instantiated. All in-progress and pending runs are canceled. If you have thousands of runs, cancellation might take significant time to complete.

Troubleshooting

When you open your logic app project in the Logic Apps Designer, you might not get the option for selecting your Azure subscription. Instead, your logic app opens with an Azure subscription that's not the one you want to use. This behavior happens because after you open a logic app's .json file, Visual Studio caches the first selected subscription for future use. To resolve this problem, try one of these steps:

  • Rename the logic app's .json file. The subscription cache depends on the file name.

  • To remove previously selected subscriptions for all logic apps in your solution, delete the hidden Visual Studio settings folder (.vs) in your solution's directory. This location stores your subscription information.
