Deploying the Functions runtime as a private site extension

If you already have a Functions app, you can use the following steps to deploy your own Functions runtime as a private site extension:

• In VS, right click the WebJobs.Script.WebHost project and choose Publish
• Select the existing File System profile and click Publish. This will create the bits under src\WebJobs.Script.WebHost\Publish
• Go to the Kudu Console for the function app that you want to use your bits on
• Drag and drop the SiteExtensions folder from your machine (in src\WebJobs.Script.WebHost\Publish), into the root of your Kudu Console. i.e. this should create d:\home\SiteExtensions\Functions
• In the Kudu Process Explorer, kill the main site (the w3wp that doesn't say scm)

You are now using your private Functions runtime.
