This exam measures your ability to accomplish the technical tasks listed below.

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
  

This exam is intended for developers with one or more years of experience programming the essential business/application logic for a variety of application types and hardware/software platforms using C#.
