AddMvc Logs DPAPI Error

Closed this issue · 4 comments

Summary
When calling AddMvc from IServiceCollection, the following error is logged in the console.
Looking for a workaround to correct it, or redirect logging for ASP.NET Core. Thanks for your time!

Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager:Information: User profile 
is available. Using 'C:\Users\Gareth\AppData\Local\ASP.NET\DataProtection-Keys' as key 
repository and Windows DPAPI to encrypt keys at rest.

    User profile is available. Using 'C:\Users\Gareth\AppData\Local\ASP.NET\DataProtection-Keys' 
as key repository and Windows DPAPI to encrypt keys at rest.

Version
DotNet 2.0.3

Startup.cs

public class Startup {
        public IConfiguration Configuration { get; }
        public Startup(IConfiguration configuration) {
            Configuration = configuration;
        }

        public void ConfigureServices(IServiceCollection services) {            
            services.AddMvc();
        }
}

That is an info entry, not an error entry. Have you perhaps enabled verbose logging in your application?

Thanks for the quick reply, and I don't believe I am. Here's my appsettings.json file:

{
    "Logging": {
      "IncludeScopes": false,
      "Debug": {
        "LogLevel": {
          "Default": "Warning"
        }
      },
      "Console": {
        "LogLevel": {
          "Default": "Warning"
        }
      }
    }
  }

and my launch.json file:

{
   // Use IntelliSense to find out which attributes exist for C# debugging
   // Use hover for the description of the existing attributes
   // For further information visit https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md
   "version": "0.2.0",
   "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/bin/Debug/netcoreapp2.0/Comet.dll",
            "args": [],
            "cwd": "${workspaceFolder}/bin/Debug/netcoreapp2.0/",
            "console": "internalConsole",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart",
            "env": {
                "ASPNETCORE_ENVIRONMENT": "Development"
            },
            "sourceFileMap": {
                "/Views": "${workspaceFolder}/src/Web/Views"
            },
            "logging": {
                "engineLogging": false,
                "moduleLoad": false
            }
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        }
    ]
}

And how I'm building the service:

static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args).UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseStartup<Startup>()
                .Build();

Is there anything I could add to my launch file's logging section to disable info logging for the DPAPI? Thanks again.

@anurse could you help direct this to the logging owner? I don't recall who the right contact is at the moment. Thanks :)

Figured it out with some reading:
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/logging/?tabs=aspnetcore2x

dotnet add package Microsoft.Extensions.Logging

WebHost.CreateDefaultBuilder(args).UseKestrel()
    .UseContentRoot(Directory.GetCurrentDirectory())
    .ConfigureLogging(logging => logging.SetMinimumLevel(LogLevel.Warning))
    .UseStartup<Startup>()
    .Build();

Took a bit of learning, but I get how logging works now. Thanks for the pointers!
