Objective Domain Note: This document shows tracked changes that are effective as of December 14, 2017.  Manage Program Flow (25-30%) Implement multithreading and asynchronous processing Use the Task Parallel library, including theParallel.For method, 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, including SQL exceptions, network exceptions, communication exceptions, network timeout exceptions; use catch statements; use base class of an exception; implement try-catchfinally blocks; throw exceptions; rethrow an exception; create custom exceptions; handle inner exceptions; handle aggregate exceptions  Create and Use Types (25-30%)   Create types Create value types, including structs and enum; create reference types, generic types, constructors, static variables, methods, classes, extension methods; create optional and named parameters; create 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 that accesses COM APIs Enforce encapsulation  Enforce encapsulation by using properties; enforce encapsulation by using accessors, including public, private, protected, and internal; enforce encapsulation 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 Lambda expressions; use types from the System.Reflection namespace, including 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; use string interpolation   Debug Applications and Implement Security (25-30%) Validate application input  Validate JSON data; choose the appropriate data collection type; manage data integrity; evaluate a regular expression to validate the input format; use built-in functions to validate data type and content  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 preprocessor compiler directives; choose an appropriate build type; manage programming program database files and (debug 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 (25-30%) 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, including projection, join, group, take, skip, aggregate; create methodbased 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
