To be able to use this preview binding extension in your app, you must reference a preview extension bundle that includes it.
Add or replace the following code in your host.json file, which specifically targets the latest preview version of the 4.x bundle:
{
"version": "2.0",
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle.Preview",
"version": "[4.0.0, 5.0.0)"
}
}Select the previous link to verify that the latest preview bundle version does contain the preview extension.
