You are developing an ASP.NET MVC application by using Visual Studio.
The application throws and handles exceptions when it runs.
You need to examine the state of the application when exceptions are thrown.
What should you do?

• A.Add the following code to the web.config file of the application.
  < customErrors mode="On" >
  < error statusCode="404" redirect="CustomErrors.html" />
  < /customErrors>
• B.From the Debug menu in Visual Studio, select Exceptions. Disable the User-unhandled check box for Common Language Runtime Exceptions.
• C.Add the following code to the web.config file of the application.
  < customErrors mode="On" >
  < error statusCode="500" redirect="CustomErrors.html" />
  < /customErrors>
• D.From the Debug menu in Visual Studio, select Exceptions. Enable the Thrown check box for Common Language Runtime Exceptions.

Correct Answer: D

Configuring the debugger to break for first chance exceptions
To change when the debugger breaks, go to Debug->Exceptions...

0121
When you first open this window you will see that there is a tree grid with one column and checkboxes.
* Break when Thrown. This includes a default list of exceptions known by the debugger, grouped by category.
Note: The possible exceptions that could break from this list is determined by the runtime you are debugging. For example, if you are using managed-only debugging then the debugger will never break for C++, Win32 Exceptions, etc. even if they are configured to break when thrown.
* Checkboxes. If you check the box for a category, then the debugger will break for all First
Chance Exceptions while debugging. If you don't want to enable all First Chance
Exceptions, you can find the specific exception types that you wish to configure by using the search box.

You are developing an ASP.NET Core MVC web application that uses custom security middleware. The middleware will add a response header to stop pages form loading when reflected cross-site scripting (XSS) attacks are detected.
The security middleware component must be constructed once per application lifetime.
You need to implement the middleware.
How should you complete the code? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation

Box 1: return _next(httpContext);
Example:
public Task Invoke(HttpContext httpContext)
{
httpContext.Response.Headers.Add("X-Xss-Protection", "1");
httpContext.Response.Headers.Add("X-Frame-Options", "SAMEORIGIN");
httpContext.Response.Headers.Add("X-Content-Type-Options", "nosniff");
return _next(httpContext);
}
Box 2: UseSecurityMiddleware
Box 3: UseMiddleware<SecurityMiddleware>()
Example:
public static class SecurityMiddlewareExtensions
{
public static IApplicationBuilder UseSecurityMiddleware(this IApplicationBuilder builder)
{
return builder.UseMiddleware<SecurityMiddleware>();
}
}
Box 4: UseSecurityMiddleware
The Extensions part is optional, but it does allow you to write code like this :
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseMiddleware<SecurityMiddleware>(); //If I didn't have the extension method app.UseSecurityMiddleware(); //Nifty encapsulation with the extension
}
