Explanation: http://msdn.microsoft.com/en-us/library/hh549176.aspx 

Shim types are one of two technologies that the Microsoft Fakes Framework uses to let you easily isolate components under test from the environment. Shims divert calls to specific methods to code that you write as part of your test. Many methods return different results dependent on external conditions, but a shim is under the control of your test and can return consistent results at every call. This makes your tests much easier to write.

Q65. - (Topic 4) 

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. 

Answer:

Explanation: Configuring the debugger to break for first chance exceptions 

To change when the debugger breaks, go to Debug->Exceptions… 

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.

Answer:

Explanation: When implementing a custom membership provider, you are required to inherit the MembershipProvider abstract class. There are two primary reasons for creating a custom membership provider. You need to store membership information in a data source that is not supported by the membership providers included with the .NET Framework, such as a FoxPro database, an Oracle database, or other data source. You need to manage membership information using a database schema that is different from the database schema used by the providers that ship with the .NET Framework. A common example of this would be membership data that already exists in a SQL Server database for a company or Web site.
