-	// [Optional] To reuse of your local HTTPS dev cert:
-	//
-	// 1. Export it locally using this command:
-	//    * Windows PowerShell:
-	//        dotnet dev-certs https --trust; dotnet dev-certs https -ep "$env:USERPROFILE/.aspnet/https/aspnetapp.pfx" -p "SecurePwdGoesHere"
-	//    * macOS/Linux terminal:
-	//        dotnet dev-certs https --trust; dotnet dev-certs https -ep "${HOME}/.aspnet/https/aspnetapp.pfx" -p "SecurePwdGoesHere"
-	// 
-	// 2. Uncomment these 'remoteEnv' lines:
-	//    "remoteEnv": {
-	// 	      "ASPNETCORE_Kestrel__Certificates__Default__Password": "SecurePwdGoesHere",
-	//        "ASPNETCORE_Kestrel__Certificates__Default__Path": "/home/vscode/.aspnet/https/aspnetapp.pfx",
-	//    },
-	//
-	// 3. Do one of the following depending on your scenario:
-	//    * When using GitHub Codespaces and/or Remote - Containers:
-	//      1. Start the container
-	//      2. Drag ~/.aspnet/https/aspnetapp.pfx into the root of the file explorer
-	//      3. Open a terminal in VS Code and run "mkdir -p /home/vscode/.aspnet/https && mv aspnetapp.pfx /home/vscode/.aspnet/https"
-	//
-	//    * If only using Remote - Containers with a local container, uncomment this line instead:
-	//      "mounts": [ "source=${env:HOME}${env:USERPROFILE}/.aspnet/https,target=/home/vscode/.aspnet/https,type=bind" ],
-
-	// Use 'postCreateCommand' to run commands after the container is created.
