Upgrading from dnx to vs2017 aspnetcore

Question

So I just installed VS2017 and loaded my application. It asked to migrate and there were a tonne of issues which I have now fixed. The last remaining issues are the following:

The first one I hope will solve the second. When I try to debug my application it states that:

the project doesnt know how to run the profile iis express

When I go to the project properties, I can see in the Debug tab, there is a IISEXPRESS profile which launches iisexpress. The other two options in the dropdown are Project and Executable . I would like to know where the IISExpress is pulled from. That obviously needs modifying but it's not like the other two options (which can be changed in the IDE).

Does anyone know how to change it?

Update

It looks like the settings are saved in the launchSettings.json file. I added this:

"profiles": {
    "IIS Express": {
        "commandName": "IISExpress",
        "launchBrowser": true,
        "environmentVariables": {
            "ASPNETCORE_ENVIRONMENT": "Development"
        }
    }
}

but still get the same error.

Answer 1

This error occurred to me, I use Visual Studio 2019:

The project doesn't know how to run the profile IIS Express.

Solution: I updated Visual Studio 2019 to the latest version

Tools -> Get tools and features

Everything worked fine again!

Installed version: Microsoft Visual Studio Community 2019 Versão 16.6.5

Looks like there is a typo in your launchSettings.json

  "profiles": {
    "IIS Express": {
    "commandName": "IISExpress",
    "launchBrowser": true,
    "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
     }
    },
