 You have the option to either deploy the Azure Function code from your Visual Studio Code to Azure or create an empty Azure Function that points to a Zip file hosted by us, containing the function code. Follow one of the two sets of instructions that follow:

-- Build and deploy the [Azure function](LoraKeysManagerFacade). The best way is to open the  [Azure function folder](LoraKeysManagerFacade) with Visual Studio Code with the [Azure Functions Plugin](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-azurefunctions) installed. Now run the command `Azure Functions: Deploy to function app...` and provide the name of the Azure function to deploy to. If prompted, select  environment `C#` and  version `V2`.
+On your Visual Studio Solution, right click on the 'LoRaKeysManagerFacade' project, select 'deploy', then 'Azure' and then 'Azure function'. You should then arrive on a page where you just need to hit the deploy button to get the code deployed on Azure.

(Unfortunately at time of this writing we saw the behavior that VSCode is proposing the wrong folder). Building the function does not work in this way unfortunately.
