Exception Handling

ASP.NET Zero uses ABP's exception handling system. Thus, you don't need to handle & care about exceptions in most time.

ASP.NET Zero solution adds exception handling middlewares in the Startup class like that:

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}
else
{
    app.UseStatusCodePagesWithRedirects("~/Error?statusCode={0}");
    app.UseExceptionHandler("/Error");
}

So, you get a nicely formatted exception page in development and a more user friendly error page in production. See ErrorController and it's related views (Views\Error) for details.
