 ## Tips
 You can use the [XDT tranform task](https://marketplace.visualstudio.com/items?itemName=qetza.xdttransform) to inject tokens in your XML based configuration files configured for local development and then use the [Replace Tokens task](https://marketplace.visualstudio.com/items?itemName=qetza.replacetokens) to replace those tokens with variable values:
