Description
Before filing this issue, please ensure you're using the latest CLI by running `swa --version` and comparing to the latest version on [npm](https://www.npmjs.com/package/@azure/static-web-apps-cli).
**Are you accessing the CLI from the default port `:4280` ?**
- [x] Yes, I am accessing the CLI from port `:4280`
> Make sure you are accessing the URL printed in the console when running `swa start`!
**ℹ️ NOTE: Make sure to enable debug logs when running any `swa` commands using `--verbose=silly`**
**Describe the bug**
A clear and concise description of what the bug is.
The **swa cli** and Visual Studio debugger no longer connect to the Blazor static web app under Visual Studio 17.8.6.
Under **Visual Studio 17.8.5** the **swa cli** will correctly launch and attach to the browser (in my case Microsoft Edge), however under **Visual Studio 17.8.6** the browser launches however the **swa cli** fails to connect with a 'Failed to launch debug adapter' error (see screenshot below).
Note: When running with **--verbose=silly** the last message is [swa] Connected to tcp:localhost:5000 successfully with no further debug messages.
**To Reproduce**
Steps to reproduce the behavior:
1. Clone the Blazor-Basic SWA from the Microsoft [Quickstart: Build your first static web app](https://learn.microsoft.com/en-us/azure/static-web-apps/get-started-portal?tabs=blazor&pivots=github#create-a-repository) instructions.
2. Update the **BlazorBasic\Properties\launchSettings.json** file by adding "launchUrl": "http://localhost:4280" and changing **applicationUrl** to be "applicationUrl": "http://localhost:5000".
The full launchSettings.json should look like:
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:42316",
"sslPort": 44363
}
},
"profiles": {
"BlazorBasic": {
"commandName": "Project",
"dotnetRunMessages": true,
"launchBrowser": true,
"launchUrl": "http://localhost:4280",
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}",
"applicationUrl": "http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
3. Start the **swa cli** with the command swa start http://localhost:5000.
4. Launch the application in Visual Studio with debugging using the **BlazorBasic** profile.
**Expected behavior**
A clear and concise description of what you expected to happen.
The **swa cli** and Visual Studio debugger should connect and launch the Blazor static web app correctly as it did with Visual Studio 17.8.5.
