SWA CLI and Visual Studio debugger does not connect in Visual Studio 17.8.6
Before filing this issue, please ensure you're using the latest CLI by running swa --version and comparing to the latest version on npm.
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:
- Clone the Blazor-Basic SWA from the Microsoft Quickstart: Build your first static web app instructions.
- 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.
