Skills measured

This exam measures your ability to accomplish the technical tasks listed below. The percentages indicate the relative weight of each major topic area on the exam. The higher the percentage, the more questions you are likely to see on that content area on the exam.

Please note that the questions may test on, but will not be limited to, the topics described in the bulleted text.

Manage program flow (25%)

  • Implement multithreading and asynchronous processing
    • Use the Task Parallel library (ParallelFor, Plinq, Tasks); create continuation tasks; spawn threads by using ThreadPool; unblock the UI; use async and await keywords; manage data by using concurrent collections
  • Manage multithreading
    • Synchronize resources; implement locking; cancel a long-running task; implement thread-safe methods to handle race conditions
  • Implement program flow
    • Iterate across collection and array items; program decisions by using switch statements, if/then, and operators; evaluate expressions
  • Create and implement events and callbacks
    • Create event handlers; subscribe to and unsubscribe from events; use built-in delegate types to create events; create delegates; lambda expressions; anonymous methods
  • Implement exception handling
    • Handle exception types (SQL exceptions, network exceptions, communication exceptions, network timeout exceptions); catch typed vs. base exceptions; implement try-catch-finally blocks; throw exceptions; determine when to rethrow vs. throw; create custom exceptions

Create and use types (24%)

  • Create types
    • Create value types (structs, enum), reference types, generic types, constructors, static variables, methods, classes, extension methods, optional and named parameters, and indexed properties; create overloaded and overriden methods
  • Consume types
    • Box or unbox to convert between value types; cast types; convert types; handle dynamic types; ensure interoperability with unmanaged code, for example, dynamic keyword
  • Enforce encapsulation
    • Enforce encapsulation by using properties, by using accessors (public, private, protected), and by using explicit interface implementation
  • Create and implement a class hierarchy
    • Design and implement an interface; inherit from a base class; create and implement classes based on the IComparable, IEnumerable, IDisposable, and IUnknown interfaces
  • Find, execute, and create types at runtime by using reflection
    • Create and apply attributes; read attributes; generate code at runtime by using CodeDom and lambda expressions; use types from the System.Reflection namespace (Assembly, PropertyInfo, MethodInfo, Type)
  • Manage the object life cycle
    • Manage unmanaged resources; implement IDisposable, including interaction with finalization; manage IDisposable by using the Using statement; manage finalization and garbage collection
  • Manipulate strings
    • Manipulate strings by using the StringBuilder, StringWriter, and StringReader classes; search strings; enumerate string methods; format strings

Debug applications and implement security (25%)

  • Validate application input
    • Validate JSON data; data collection types; manage data integrity; evaluate a regular expression to validate the input format; use built-in functions to validate data type and content out of scope: writing regular expressions
  • Perform symmetric and asymmetric encryption
    • Choose an appropriate encryption algorithm; manage and create certificates; implement key management; implement the System.Security namespace; hashing data; encrypt streams
  • Manage assemblies
    • Version assemblies; sign assemblies using strong names; implement side-by-side hosting; put an assembly in the global assembly cache; create a WinMD assembly
  • Debug an application
    • Create and manage compiler directives; choose an appropriate build type; manage programming database files and symbols
  • Implement diagnostics in an application
    • Implement logging and tracing; profiling applications; create and monitor performance counters; write to the event log

Implement data access (26%)

  • Perform I/O operations
    • Read and write files and streams; read and write from the network by using classes in the System.Net namespace; implement asynchronous I/O operations
  • Consume data
    • Retrieve data from a database; update data in a database; consume JSON and XML data; retrieve data by using web services
  • Query and manipulate data and objects by using LINQ
    • Query data by using operators (projection, join, group, take, skip, aggregate); create method-based LINQ queries; query data by using query comprehension syntax; select data by using anonymous types; force execution of a query; read, filter, create, and modify data structures by using LINQ to XML
  • Serialize and deserialize data
    • Serialize and deserialize data by using binary serialization, custom serialization, XML Serializer, JSON Serializer, and Data Contract Serializer
  • Store data in and retrieve data from collections
    • Store and retrieve data by using dictionaries, arrays, lists, sets, and queues; choose a collection type; initialize a collection; add and remove items from a collection; use typed vs. non-typed collections; implement custom collections; implement collection interfaces
