[Blazor] debugging startup takes 24 seconds while without it loads instantly

Is there an existing issue for this?

• [X] I have searched the existing issues

Describe the bug

After I set up my enterprise-grade solution, debug startup time increased from 5 seconds which is pretty nice to 24-28 seconds which is not acceptable

Expected Behavior

Debugging startup time takes no more than 10 seconds

Steps To Reproduce

1. dotnet new -i Bolero.Templates

2. dotnet new bolero-app -o MyBoleroApp

3. Add "inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}", to launchSettings.json as per https://github.com/fsbolero/Bolero/issues/307#issuecomment-1593158277

4. Run in debug mode and see that app loads in 5 seconds

5. unpack App.zip and run in debug mode Marketplace.Server

6. See that it loads very slow!

Exceptions (if any)

Yes, with me on 17.6.4 it takes up to 12 seconds to download the browserLink:

Not sure if it's the same issue but it's quite a wait to start every time with the debugger!

Looks like it was fixed in 8.0
