Describe the bug

hi

I want log client blazor errors
via custom ilogger / ilogger provider like it should be but i want to sent it to api via httpclient. so i have in program.cs

     builder.Services.AddHttpClient("BlazorApp_issue_ilogger.ServerAPI", client => client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress));
     builder.Services.AddSingleton<ILoggerProvider, DbLoggerProvider>();

so now i want to build my LoggerProvider

public class DbLoggerProvider : ILoggerProvider
{
  private readonly IOptions<DbLoggerProvider> _options;
  private readonly IServiceProvider _isp;
  private readonly IHttpService _httpService;

     public class DbLoggerProvider : ILoggerProvider
     {
        private readonly IOptions<DbLoggerProvider> _options;
        private readonly IServiceProvider _isp;
          private readonly HttpClient _httpService;

       public DbLoggerProvider(IOptions<DbLoggerProvider> options, IServiceProvider isp)
     {
         _options = options;
        _isp = isp;
         _httpService = _isp.CreateScope().ServiceProvider.GetRequiredService<HttpClient>();
     }

and this compile fine but freaze app on 'loading'

if i simply comment out this _http part

      _httpService = _isp.CreateScope().ServiceProvider.GetRequiredService<HttpClient>();

then it compiles fine also and works as usual - without any freeze

i checked also

      public DbLoggerProvider(IOptions<DbLoggerProvider> options, IServiceProvider isp, IHttpClientFactory httpClientFactory)

or

      public DbLoggerProvider(IOptions<DbLoggerProvider> options, IServiceProvider isp, HttpClient httpClient)

but result is the same - same loading freeze if i want IHttpClientFactory / Httpclient in ctor.

why this is happening ? is it some .net bug? why i canot inject it here? thanks and regards

Expected Behavior

it should allow to inject or create somehow this http service instance here also and not 'hang' ?

Steps To Reproduce

https://github.com/d00lar/BlazorApp-issue-ilogger

Exceptions (if any)

none

.NET Version

7

Anything else?

if this is not allowed because of something then some error message should be thrown ?

thanks and regards

Hello, I don't know if that question is still actual. I'm fighting with exactly same problem. I suppose the app freezing is because you are trying to inject a scoped service (Http) to a singleton service (LoggerProvider). It can't resolve that. Instead you can try to inject in your provider IServiceScopeFactory and then give it to your logger. After that you can use it like this: using (var scope = _serviceScopeFactory.CreateScope()) { var http = scope.ServiceProvider.GetService();

            var response = await http.PostAsJsonAsync($"{EndPoints.SendUiLogs}", logs);

            response.EnsureSuccessStatusCode();
            return true;
        }

It's not a beautiful solution, but it works. Hope it helps. This is article to help understand that issue: https://samwalpole.com/using-scoped-services-inside-singletons

@d00lar, does @Andrey10183's suggestion solve the problem you're experiencing?

it does not solve this / it is the same thing as in my code / he only replaced GetRequiredService with GetService / this work when injecting scope to singelton YES but NOT when i want do do this in ILoggerProvider / ILoggerProvider is special somehow in this case. please resolve this somehow / add some message that not allowed somehow or it should work i think
