I am wondering if i am missing something but just started a basic template for server side Blazor and find that Console.WriteLine does not work. By that I mean I can't see the text in Chrome Console.

@code{

    protected override async Task OnInitializedAsync() 
    {
        System.Console.WriteLine("oninit");
    }
}

I had to do something like this to make text show in the browser console:

@inject IJSRuntime jsRuntime

@code {

    protected override async Task OnInitializedAsync()
    {
        await jsRuntime.InvokeAsync<string>("console.log", "hello world");
    }
}
