This is the first time installing VS2022 on this computer.

Any new projects I have tried launching from Visual Studio seems to launch without error but when I try to load the application through the browser I just get a 404 error.

Here is my launch configuration although, I get the same issue when launching a new core web app…

{
  "profiles": {
    "Kestrel": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": true,
      "applicationUrl": "http://localhost:5238"
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "DotNet Commandline": {
      "commandName": "Executable",
      "executablePath": "C:\Program Files\dotnet\dotnet.exe",
      "commandLineArgs": "run --configuration Debug",
      "workingDirectory": "C:\Users\jcarr\Workspace\ProductionOutageTracker\Web",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  },
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": true,
    "anonymousAuthentication": false,
    "iisExpress": {
      "applicationUrl": "http://localhost:36511",
      "sslPort": 0
    }
  }
}

I have tried various launch configurations without success. I have tried creating a brand-new application and I have the same problem, so I don’t believe it’s anything in my program.cs that is failing.

The only thing I have found that works is using the dotnet run command, which I can setup in launch configurations and launch from Visual Studio but then my debug breakpoints gets the error “symbols have not been loaded for this document”
