I am new to programming, I am trying to implement a logging solution for .net core project.
I want to collect Default and Microsoft category logs.
APPSETTING.JSON
{
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"System": "Warning",
"Microsoft": "Information"
},
"File": {
"location": "logs/timeapi.log"
}
},
"EnableSwagger": true
}
PROGRAM.CS
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSerilogRequestLogging();
STARTUP.CS
app.UseSerilogRequestLogging(options =>
options.RequestProjection =
r => new { r.IsHttps, QueryString = r.QueryString.Value });
app.UseMvc();
https://github.com/mthamil/AspNetCore.Serilog.RequestLoggingMiddleware
The error I am getting is :
Unable to resolve service for type 'Serilog.ILogger' while attempting to activate 'AspNetCore.Serilog.RequestLoggingMiddleware.SerilogRequestMiddleware'.
The middleware you're using appears to need Serilog's ILogger
added in the app's Startup.ConfigureServices()
method ; eg:
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<ILogger>(Log.Logger);
}
(This example assumes you're configuring Serilog's Log.Logger
static property.)
There's a more complete example of setting up request logging with Serilog in the readme for the Serilog.AspNetCore package , though its implementation of UseSerilogRequestLogging()
is quite different.
if you are using .net core 3.1 + only use it in program.cs like this and remove every thing about Serilog from startup.cs
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
.WriteTo.Console())
......;
