Selgitage asünkroonsuse tööpõhimõtet korutinates ja kuidas see on rakendatud

Asynchronous in coroutines in C# is implemented using the keywords async and await, which allow writing asynchronous code that resembles synchronous code, without blocking threads.

Working principle:

• A method marked as async can contain the await operator, which suspends the method execution until the asynchronous operation completes.
• During this time, the current thread is not blocked, and control is returned to the calling code.
• After the operation completes, the method execution continues from the await point.

Example:

public async Task<string> GetDataAsync()
{
    // Asynchronously wait for the operation to complete
    string result = await SomeLongRunningOperationAsync();
    return result;
}

Thus, coroutines allow efficient resource utilization without blocking threads during waiting.
