"The following site was not found in the configuration file..." when starting IIS Express from within VS Code

[patrick-lim]

Just as a test, I created a web application, launched VS Code, installed the Extension and fired up IIS Express. I get...

The following site was not found in the configuration file: 'test5-6cccf563-3792-40fa-a7c2-aecbbac2fd75'

In my launchsettings.json file, I have this:

{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:26944",
"sslPort": 44394
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"test5": {
"commandName": "Project",
"launchBrowser": true,
"applicationUrl": "https://localhost:5001;http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}

Hi @patrick-lim
This is currently not supported to use the applicationhost.config file.

It’s something I want to look into soon & was reported in this issue #33

I will close this issue as it’s a duplicate

That's not a duplicate - I have don't have applicationhost.config either, but launch fails with "The following site was not found in the configuration file: 'xxx-9c9bfb49-e198-4318-b49f-fd70d2ad75cb'".
