I am trying to log my logged in user details in the logger file using serilog, to get the user info from decrypting in the token in dot net core API

Hi,

You can do something like this.
app.UseSerilogRequestLogging(options =>
    {
         options.EnrichDiagnosticContext = PushSeriLogProperties;
    });



    public void PushSeriLogProperties(IDiagnosticContext diagnosticContext, HttpContext httpContext)
    {
            diagnosticContext.Set("SomePropertyName", httpContext.User...);
    }

You can use middleware as shown:
public class LogUserNameMiddleware
{
    private readonly RequestDelegate next;

    public LogUserNameMiddleware(RequestDelegate next)
    {
        this.next = next;
    }

    public Task Invoke(HttpContext context)
    {
        LogContext.PushProperty("UserName", context.User.Identity.Name);

        return next(context);
    }
}
Also you need to add the following to your logger configuration:
.Enrich.FromLogContext()
In Startup add the middleware LogUserNameMiddleware, and also note that the middleware should be added after UserAuthentication, in order to have context.User.Identity initialized
app.UseAuthentication();

app.UseMiddleware();
