First, the async keyword indicates to C# that the method is asynchronous, meaning that it may use an arbitrary number of await expressions and will bind the result to a promise. [1]: 165–168 The return type, Task<T>, is C#'s analogue to the concept of a promise, and here is indicated to have a result value of type int.
A simple way to understand wait (P) and signal (V) operations is: wait: Decrements the value of the semaphore variable by 1. If the new value of the semaphore variable is negative, the process executing wait is blocked (i.e., added to the semaphore's queue). Otherwise, the process continues execution, having used a unit of the resource.
C# is case sensitive and all C# keywords are in lower cases. Visual Basic and C# share most keywords, with the difference being that the default Visual Basic keywords are the capitalised versions of the C# keywords, e.g. Public vs public , If vs if .

C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.

The parent process may then issue a wait system call , which suspends the execution of the parent process while the child executes.
