Describe the bug
When attempting to debug a local IIS hosted web application running blazor you get an error when attempting to debug the blazor razor component.
Kestrel debugging works fine. However it is broken in IIS mode when running under an SSL certificate:
Unable to launch browser: \"Could not open wss://localdev.arrt.org:443/_framework/debug/ws-proxy?browser=ws%3A%2F%2F127.0.0.1%3A34840%2Fdevtools%2Fbrowser%2Fd2b99056-84ce-433a-819b-d7df11de4a00\
Currently the only work around is to remove the following from the launchSettings.json, but then blazor components using WebAssemblyPrerendered are no longer able to be debugged.
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}",
Here is the log indicating it is unable to open a websocket connection.
visualstudio-js-debugger.txt
NOTE: IIS does have Websocket Protocol enabled in windows, so that is not the issue. Other websocket activities work fine, just not the debugging using inspectUri parameter.
This may be related to this issue: https://github.com/dotnet/runtime/issues/96239
However the fix indicated in that issue does not work for me. This is the fix recommended (updated example to LocalDevelopment):
<DebuggerSupport Condition="'$(Configuration)' == 'LocalDevelopment'">true</DebuggerSupport>
Expected Behavior
Client side debugging should work without issue. The "inspectUri": "{wsProtocol}://{url.hostname}:443/_framework/debug/ws-proxy?browser={browserInspectUri}" line should also work without issue when running within IIS under an SSL certificate.
