title: Replace tokens in all .config files in an Azure Web App
body: <p>I have set up my environment variables which are successfully replaced on the on-prem test environments using the <em>Replace tokens in files</em> task in a <em>Deployment group phase</em>. I am now deploying to an <em>Azure App Service</em> and I'm wondering how to achieve the token replacement given that the tokens are in the format: <code>#{tokenname}#</code> and I want to replace tokens in files that match the pattern: <code>**/*.config</code>. I've had a look at enabling XML variable substitution within the Azure App Service Deploy step but this doesn't seem to target all tokens in all config files.</p>
