Synchronizing Threads

Understand the challenges of shared resources in multithreaded C# applications and learn how to use synchronization to prevent race conditions. Explore critical sections and techniques to ensure thread-safe operations for predictable, reliable program behavior.

Having multiple threads in an application allows us to perform several tasks in parallel. When different threads work with shared resources, such as a global variable or a file, we must consider the potential for conflicts.

Using shared resources

Consider a banking scenario where we have a shared balance variable. Before we add multithreading, let’s look at how a simple deposit operation works normally.

The Deposit() method adds $100 to the balance. If we call this method sequentially (one after another), the logic is predictable ...
