You need to create, maintain, and inject dependencies in the unit tests.

Which isolation method should you use?

A. T4 text templates and code generation

B. Stub types

C. Shim types

D. Hard-coded implementation

Answer: C

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.

Example:

EtwProviders>

<EtwEventSourceProviderConfiguration provider="SampleEventSourceWriter"

scheduledTransferPeriod="PT5M">

Answer: D

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.
