SerilLog not logging in web application

Question

On my WebUI project startUp.cs class i have

        public Startup()
    {
        Log.Logger = new LoggerConfiguration()
                   .WriteTo.Console()
                   .CreateLogger();
    }

and in my class library project sample.cs class i am calling

                Log.Logger.Information("This will be written to the rolling file set");

the both using serilog and class library has webUI reference but nothing happens.

Any ideas?

i have already tried it in a sample wpf project and it works fine, it logs to console and file but not in class library/web app — DisplayName, Jun 02 '17 at 09:58
Just a note, you can use `Log.Information()` as a shortcut version of `Log.Logger.Information()`. — Nicholas Blumhardt, Jun 03 '17 at 01:23

If the web app is running under IIS, you won't get output via the console. It's also likely that the app pool account IIS is using won't have access to many local paths. The trick here is usually finding a local path with valid permissions.

You can get additional diagnostics from Serilog's internal log: https://github.com/serilog/serilog/wiki/Debugging-and-Diagnostics
