## Problem

For Azure web apps using the `NewRelic.Azure.WebSites.Extension`, and deployed with Azure Pipelines, the `newrelic` directories are deleted, so no instrumentation occurs. Further attempts to deploy using the Azure Pipeline indicate that the `NewRelic.Azure.WebSites.Extension` is already installed, so the extension cannot be re-installed using the Azure Pipeline.

## Solution

To control `newrelic` folder retention, use the following options for WebDeploy:

| Enable `skipAction=Delete` WebDeploy arguments. | Explicitly exclude specific folders from deletion, such as the `newrelic` folders, with the following: Azure Pipelines UI: Add these arguments to the **Azure App Service deploy -> Additional Deployment Options -> Additional Arguments** ```` -skip:skipAction=Delete,objectName=dirPath,absolutePath='newrelic$' -skip:skipAction=Delete,objectName=dirPath,absolutePath='newrelic_core$' ```  OR  `Pipeline.yml` file:  add the following `input` to the WebDeploy task:  ```yml AdditionalArguments: '-skip:skipAction=Delete,objectName=dirPath,absolutePath=''newrelic$'' -skip:skipAction=Delete,objectName=dirPath,absolutePath=''newrelic_core$''' ```  <DNT>**Note**</DNT> the escaped single quotes.  ```` |

## Cause

If the `Remove additional files at destination` option is selected for the `AzureRmWebAppDeployment` task in the Azure Pipeline, the `newrelic` and `newrelic_core` directories are deleted from `wwwroot`, but the extension is not considered uninstalled by Azure. As a result, the next time the pipeline runs and attempts to install the extension, the pipeline displays the message `Extension 'NewRelic.Azure.WebSites.Extension' already installed.` The extension cannot run without its folders, and Azure will not re-install it because it considers it still installed.
