VS 2022 "Unable to connect to web server 'IIS Express'"

Hello I want to apply Hsts (Strict-Transport-Security) and I want to implement and test in my local.
But i can't change my application Url from http to https version . I tried solutions on other answers but did not worked. I tried 443 port / I tried delete .vs config file but it does not exist.
{

"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "https://localhost:47000",// This was working http
"sslPort": 0
}
},

Debugging the remote connection was closed when use Blazor

I use Visual Studio Enterprise 2022 (64-bit) version 17.4, .Net 7, and BlazorWebAssembly.
When I use BlazorWebAssembly and try to debug a Blazor client-side app, I keep getting the error
Debugging connection was closed. Reason : WebSocket disconnected
This is my code launchSettings.json
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:33139",
"sslPort": 0
}
},
"profiles": {
"BlazorApp": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}",
"applicationUrl": "http://localhost:5149",
"dotnetRunMessages": true
},
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}"
},
"WSL": {
"commandName": "WSL2",
"launchBrowser": true,
"launchUrl": "http://localhost:5149",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development",
"ASPNETCORE_URLS": "http://localhost:5149"
},
"distributionName": ""
}
}
}
I try this Debug ASP.NET Core Blazor WebAssembly
but it doesn't work.

Add app.UseBlazorDebugging(); inside the if (env.IsDevelopment()) block in Startup.cs will resolved your issue.

.Net Core Project won't open browser by default

When debugging in VS 2019 the api url automatically opens which is different from the angular live url.
The angular live url is my actual complete application. Is there a way to open that url automatically when debugging?

I think you need to modify your json config a little bit. So when you use VS to run your code or using dotnet run command you will use port 59709 to run your app
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:59709/",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"ancmHostingModel": "InProcess"
},
"KaddaTechnologies": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:59709/"
}
}
}

VS2017 Debug: no Launch URL setting

Project (full net461, core 1.1) converted from VS2015:
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:17901/",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"WebApplication1": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
Also no browsers opens automatically after F5. (But site opens when I go to url manually).
And I also cannot create not Core web project in 2017 to see how it works - VS just writes something about "failed to create project" in bottom line and empty solution explorer, only folder created, nothing in Output, nothing in devenv /Log C:/log.xml log.

To fix: enable "Azure App service Tools"

dotnet Core: debug does not open browser after upgrade to VS2017

My launchSettings.json is (after changing launchUrl to applicationUrl):
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:5000/",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:5050/"
},
"Project Development": {
"commandName": "Project",
"launchBrowser": true,
"applicationUrl": "http://localhost:5050/"
}
}
}
Previously both profiles opened http://localhost:5050/. Now second profile just starts the server and first shows "The project doesn't know how to run the profile IIS Express" error.
