Https redirection in IIS Express

I think everyone agrees that using HTTPS for your web applications is the default. Therefore it makes sense to have the HttpsRedirection middleware always active in your ASP.NET Core application:

However when I tried to run this ASP.NET Core application using IIS Express, I always arrived at the root url of my local IIS instance(https://localhost/):

I found the source of this behaviour in the launchsettings.json file where I had only http configured:

	{
	"profiles": {
	"IIS Express": {
	"commandName": "IISExpress",
	"launchBrowser": true,
	"environmentVariables": {
	"ASPNETCORE_ENVIRONMENT": "Development"
	}
	},
	"eShopExample": {
	"commandName": "Project",
	"launchBrowser": true,
	"environmentVariables": {
	"ASPNETCORE_ENVIRONMENT": "Development"
	},
	"authenticationMode": "Windows",
	"applicationUrl": "http://localhost:42441/"
	}
	},
	"iisSettings": {
	"windowsAuthentication": true,
	"anonymousAuthentication": false,
	"iisExpress": {
	"applicationUrl": "http://localhost:42440/"
	}
	}
	}

The https middleware causes the redirect to https but as there is no IIS Express https endpoint active I end up on https://localhost (and get the default IIS web page):

The solution is to active an https endpoint by specifying the sslPort:

	{
	"profiles": {
	"IIS Express": {
	"commandName": "IISExpress",
	"launchBrowser": true,
	"environmentVariables": {
	"ASPNETCORE_ENVIRONMENT": "Development"
	}
	},
	"eShopExample": {
	"commandName": "Project",
	"launchBrowser": true,
	"environmentVariables": {
	"ASPNETCORE_ENVIRONMENT": "Development"
	},
	"authenticationMode": "Windows",
	"applicationUrl": "http://localhost:42441/"
	}
	},
	"iisSettings": {
	"windowsAuthentication": true,
	"anonymousAuthentication": false,
	"iisExpress": {
	"applicationUrl": "http://localhost:42440/",
	👇
	"sslPort": 44327
	}
	}
	}
