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

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.

launchSettings.json file opens wrong URL

When I try I couldn't run this project in my computer today but my teammates can run at their own computer. By the way I can run other projects. My launchSettings file like this:
{
"$schema": "http://json.schemastore.org/launchsettings.json",
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:4321",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
//"launchUrl": "User",
"launchUrl": "swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"Dashboard.WebAPI": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "User",
"applicationUrl": "http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
But when I run this project my url is opening as "https://localhost:4321/swagger/index.html".
I guess this problem is because this url is run as "https" but my applicationUrl is "http".
What could be the cause of this problem?
Edit:
My browser:

Either disable Https redirection in your Startup.cs/Program.cs depending whether you use .net5 or .net6 or put your sslPort value in launchSettings.json to a 4322 port (or some other of your choosing, just not any that are in use) and it'll work.
Edit:
{
"$schema": "http://json.schemastore.org/launchsettings.json",
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:4321","https://localhost:4322",
"sslPort": 4322
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
//"launchUrl": "User",
"launchUrl": "swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"Dashboard.WebAPI": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "User",
"applicationUrl": "http://localhost:5000","https://localhost:5001"
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}

On the Visual Studio toolbar their is a dropdown that allows you to select which profile to run. I suspect you are running the IIS Express profile when you want to run the Dashboard.WebAPI profile. If you see "IIS Express" on your toolbar with a green arrow to the left of it then select the dropdown and choose Dashboard.WebAPI (see mocked up image below)

Web-app hot-reload when running by IIS Express with SSL

Created project by Micosoft Visual Studio "ASP.NET with React+Redux" template. In that case app running by IIS Express. But hot-reload for react-app doesn't work and shows error in console: "WebSocket connection to 'wss://localhost:54691/ws' failed:"
After some research, I found a solution: disable SSL in IIS settings. But how can I achieve using hot reload when SSL is enabled?

.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/"
}
}
}

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.
