High level topics covered by our practice test

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.
