We need to add the list of supported language to our style guide and replace the alternative ones currently in use in our repo to the officially supported ones, since new features will be done based on those.
For example, replace ```cs with ```csharp, ```fs with ```fsharp, etc.
The list of supported identifiers can be found in this internal site:
