I try to debug a Blazor WebAssembly app in Ubuntu, using VSCode. I'm able to start the application from VSCode but it doesn't hit at any breakpoints.
What I did I followed the guides from Microsoft:
just created a new standard project using
dotnet new blazorwasm -o BlazorWasmApplication1
I'm using the original code from the template.
Properties/launchSettings.json

"anonymousAuthentication": true,

}

}
}

This is what the debug console shows me.

The application pops up in a separate window. Hovering over the breakpoint shows unbound breakpoint. And of course it doesn't stop there when executing the code.
Has anyone an idea what I'm doing wrong? Or is there any known bug? Or any alternative approaches? Thanks in advance.
