How to turn off the logging done by the ASP.NET core framework

Question

How do I turn off the logging done by ASP.NET for each request e.g.

INFO 09:38:41 User profile is available. Using \'C:\\Users\\xxxx xxxx\\AppData\\L

Answer 1

I'm not sure if I am missing something but don't you just want to raise the log level for the Microsoft logs?

Edit appsettings.json (assumes .AddJsonFile("appsettings.json", ...))

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Trace",
      "System": "Information",
      "Microsoft": "Information"

To

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Trace",
      "System": "Information",
      "Microsoft": "None"

Or the same modification via environment variables (assumes .AddEnvironmentVariables())

Logging:LogLevel:Microsoft=None

You can also be more specific, the following reduces most entries but leaves Microsoft.AspNetCore.Hosting.Internal.WebHost at Information.

"Microsoft": "Information",  
"Microsoft.AspNetCore.Mvc.Internal": "Warning",
"Microsoft.AspNetCore.Authentication":  "Warning"

Appologies if this doesn't work for log4net
