},
"Logging": {

GO3- in Asp.net Core Web Application in startup.cs add following codes:
3-1-
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
// Add This Line To access HttpContext from within the MsSqlLogger to get the user name, trace Identifier that gets error also for returning back logId inside httpContext.
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddMvc();
}3-2-
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory,
IHttpContextAccessor httpContextAccessor)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
// Add This To Log to MsSql Db
loggerFactory.AddMsSql(Configuration.GetConnectionString("LoggerConnection"), httpContextAccessor, "SampleApplication");
// Also you can add as Provider as below:
//loggerFactory.AddProvider(new MsSqlLoggerProvider((_, LogLevel) => LogLevel >= LogLevel.Trace,
// Configuration.GetConnectionString("LoggerConnection"), null,"SampleApplication"));
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}To Use in Asp.Net Web Application targetting .NetFramework you should also add following nuget packages manually to your project.
